  In the Linux kernel, the following vulnerability has been resolved: regmap: spi: Reserve space for register address/padding Currently the max_raw_read and max_raw_write limits in regmap_spi struct do not take into account the additional size of the transmitted register address and padding. This may result in exceeding the maximum permitted SPI message size, which could cause undefined behaviour, e.g. data corruption. Fix regmap_get_spi_bus() to properly adjust the above mentioned limits by reserving space for the register address/padding as set in the regmap configuration.

  In the Linux kernel, the following vulnerability has been resolved: tcp: TX zerocopy should not sense pfmemalloc status We got a recent syzbot report [1] showing a possible misuse of pfmemalloc page status in TCP zerocopy paths. Indeed, for pages coming from user space or other layers, using page_is_pfmemalloc() is moot, and possibly could give false positives. There has been attempts to make page_is_pfmemalloc() more robust, but not using it in the first place in this context is probably better, removing cpu cycles. Note to stable teams : You need to backport 84ce071e38a6 ("net: introduce __skb_fill_page_desc_noacc") as a prereq. Race is more probable after commit c07aea3ef4d4 ("mm: add a signature in struct page") because page_is_pfmemalloc() is now using low order bit from page->lru.next, which can change more often than page->index. Low order bit should never be set for lru.next (when used as an anchor in LRU list), so KCSAN report is mostly a false positive. Backporting to older kernel versions seems not necessary. [1] BUG: KCSAN: data-race in lru_add_fn / tcp_build_frag write to 0xffffea0004a1d2c8 of 8 bytes by task 18600 on cpu 0: __list_add include/linux/list.h:7

• May 3, 2024In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix out-of-bounds read when setting HMAC data.CVE-2022-48687 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67Medium 5.5

  In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix out-of-bounds read when setting HMAC data. The SRv6 layer allows defining HMAC data that can later be used to sign IPv6 Segment Routing Headers. This configuration is realised via netlink through four attributes: SEG6_ATTR_HMACKEYID, SEG6_ATTR_SECRET, SEG6_ATTR_SECRETLEN and SEG6_ATTR_ALGID. Because the SECRETLEN attribute is decoupled from the actual length of the SECRET attribute, it is possible to provide invalid combinations (e.g., secret = "", secretlen = 64). This case is not checked in the code and with an appropriately crafted netlink message, an out-of-bounds read of up to 64 bytes (max secret length) can occur past the skb end pointer and into skb_shared_info: Breakpoint 1, seg6_genl_sethmac (skb=<optimized out>, info=<optimized out>) at net/ipv6/seg6.c:208 208 memcpy(hinfo->secret, secret, slen); (gdb) bt #0 seg6_genl_sethmac (skb=<optimized out>, info=<optimized out>) at net/ipv6/seg6.c:208 #1 0xffffffff81e012e9 in genl_family_rcv_msg_doit (skb=skb@entry=0xffff88800b1f9f00, nlh=nlh@entry=0xffff88800b1b7600, extack=extack@entry=0xffffc90000ba7af0, ops=ops@entry=0xffffc90000ba7a8

  In the Linux kernel, the following vulnerability has been resolved: IB/core: Fix a nested dead lock as part of ODP flow Fix a nested dead lock as part of ODP flow by using mmput_async(). From the below call trace [1] can see that calling mmput() once we have the umem_odp->umem_mutex locked as required by ib_umem_odp_map_dma_and_lock() might trigger in the same task the exit_mmap()->__mmu_notifier_release()->mlx5_ib_invalidate_range() which may dead lock when trying to lock the same mutex. Moving to use mmput_async() will solve the problem as the above exit_mmap() flow will be called in other task and will be executed once the lock will be available.

  In the Linux kernel, the following vulnerability has been resolved: nvme: host: fix double-free of struct nvme_id_ns in ns_update_nuse() When nvme_identify_ns() fails, it frees the pointer to the struct nvme_id_ns before it returns. However, ns_update_nuse() calls kfree() for the pointer even when nvme_identify_ns() fails. This results in KASAN double-free, which was observed with blktests nvme/045 with proposed patches [1] on the kernel v6.8-rc7. Fix the double-free by skipping kfree() when nvme_identify_ns() fails.

  In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: do not realloc workqueue everytime an interface is added Commit 09ed8bfc5215 ("wilc1000: Rename workqueue from "WILC_wq" to "NETDEV-wq"") moved workqueue creation in wilc_netdev_ifc_init in order to set the interface name in the workqueue name. However, while the driver needs only one workqueue, the wilc_netdev_ifc_init is called each time we add an interface over a phy, which in turns overwrite the workqueue with a new one. This can be observed with the following commands: for i in $(seq 0 10) do iw phy phy0 interface add wlan1 type managed iw dev wlan1 del done ps -eo pid,comm|grep wlan 39 kworker/R-wlan0 98 kworker/R-wlan1 102 kworker/R-wlan1 105 kworker/R-wlan1 108 kworker/R-wlan1 111 kworker/R-wlan1 114 kworker/R-wlan1 117 kworker/R-wlan1 120 kworker/R-wlan1 123 kworker/R-wlan1 126 kworker/R-wlan1 129 kworker/R-wlan1 Fix this leakage by putting back hif_workqueue allocation in wilc_cfg80211_init.

  In the Linux kernel, the following vulnerability has been resolved: btrfs: fix race when detecting delalloc ranges during fiemap For fiemap we recently stopped locking the target extent range for the whole duration of the fiemap call, in order to avoid a deadlock in a scenario where the fiemap buffer happens to be a memory mapped range of the same file. This use case is very unlikely to be useful in practice but it may be triggered by fuzz testing (syzbot, etc). This however introduced a race that makes us miss delalloc ranges for file regions that are currently holes, so the caller of fiemap will not be aware that there's data for some file regions. This can be quite serious for some use cases - for example in coreutils versions before 9.0, the cp program used fiemap to detect holes and data in the source file, copying only regions with data (extents or delalloc) from the source file to the destination file in order to preserve holes (see the documentation for its --sparse command line option). This means that if cp was used with a source file that had delalloc in a hole, the destination file could end up without that data, which is effectively a data loss issue, if it happened

This changed the logic where, in the previous implementation the dev from the trigger event was used to check if the carrier was ok, but in the new implementation with the generic function, the dev in trigger_data is used instead. This is problematic and cause a possible kernel panic due to the fact that the dev in the trigger_data still reference the old one as the new one (passed from the trigger event) still has to be hold and saved in the trigger_data struct (done in the NETDEV_REGISTER case). On calling of get_device_state(), an invalid net_dev is used and this cause a kernel panic.

  In the Linux kernel, the following vulnerability has been resolved: USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values in the ATA ID information to calculate cylinder and head values when creating a CDB for READ or WRITE commands. The calculation involves division and modulus operations, which will cause a crash if either of these values is 0. While this never happens with a genuine device, it could happen with a flawed or subversive emulation, as reported by the syzbot fuzzer. Protect against this possibility by refusing to bind to the device if either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device's ID information is 0. This requires isd200_Initialization() to return a negative error code when initialization fails; currently it always returns 0 (even when there is an error).

  In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc4-pcm: Workaround for crashed firmware on system suspend When the system is suspended while audio is active, the sof_ipc4_pcm_hw_free() is invoked to reset the pipelines since during suspend the DSP is turned off, streams will be re-started after resume. If the firmware crashes during while audio is running (or when we reset the stream before suspend) then the sof_ipc4_set_multi_pipeline_state() will fail with IPC error and the state change is interrupted. This will cause misalignment between the kernel and firmware state on next DSP boot resulting errors returned by firmware for IPC messages, eventually failing the audio resume. On stream close the errors are ignored so the kernel state will be corrected on the next DSP boot, so the second boot after the DSP panic. If sof_ipc4_trigger_pipelines() is called from sof_ipc4_pcm_hw_free() then state parameter is SOF_IPC4_PIPE_RESET and only in this case. Treat a forced pipeline reset similarly to how we treat a pcm_free by ignoring error on state sending to allow the kernel's state to be consistent with the state the firmware will have after the next

  In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: ensure offloading TID queue exists The resume code path assumes that the TX queue for the offloading TID has been configured. At resume time it then tries to sync the write pointer as it may have been updated by the firmware. In the unusual event that no packets have been send on TID 0, the queue will not have been allocated and this causes a crash. Fix this by ensuring the queue exist at suspend time.

  In the Linux kernel, the following vulnerability has been resolved: libbpf: Use OPTS_SET() macro in bpf_xdp_query() When the feature_flags and xdp_zc_max_segs fields were added to the libbpf bpf_xdp_query_opts, the code writing them did not use the OPTS_SET() macro. This causes libbpf to write to those fields unconditionally, which means that programs compiled against an older version of libbpf (with a smaller size of the bpf_xdp_query_opts struct) will have its stack corrupted by libbpf writing out of bounds. The patch adding the feature_flags field has an early bail out if the feature_flags field is not part of the opts struct (via the OPTS_HAS) macro, but the patch adding xdp_zc_max_segs does not. For consistency, this fix just changes the assignments to both fields to use the OPTS_SET() macro.
