A flaw was found in the grub2-set-bootflag utility of grub2. After the fix of CVE-2019-14865, grub2-set-bootflag will create a temporary file with the new grubenv content and rename it to the original grubenv file. If the program is killed before the rename operation, the temporary file will not be removed and may fill the filesystem when invoked multiple times, resulting in a filesystem out of free inodes or blocks.

Jan 30, 2024A flaw was found in the Linux kernel's memory deduplication mechanism.CVE-2024-0564 · Other software · Red Hat · reported by Red HatMedium 5.3
A flaw was found in the Linux kernel's memory deduplication mechanism. The max page sharing of Kernel Samepage Merging (KSM), added in Linux kernel version 4.4.0-96.119, can create a side channel. When the attacker and the victim share the same host and the default setting of KSM is "max page sharing=256", it is possible for the attacker to time the unmap to merge with the victim's page. The unmapping time depends on whether it merges with the victim's page and additional physical pages are created beyond the KSM's "max page share". Through these operations, the attacker can leak the victim's page.

A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality.

Jan 16, 2024The Mock software contains a vulnerability wherein an attacker could potentially exploit privilege escalation, enabling the execution of arbitrary code with rooCVE-2023-6395 · Other software · Red Hat · reported by Red HatMedium 6.7
The Mock software contains a vulnerability wherein an attacker could potentially exploit privilege escalation, enabling the execution of arbitrary code with root user privileges. This weakness stems from the absence of proper sandboxing during the expansion and execution of Jinja2 templates, which may be included in certain configuration parameters. While the Mock documentation advises treating users added to the mock group as privileged, certain build systems invoking mock on behalf of users might inadvertently permit less privileged users to define configuration tags. These tags could then be passed as parameters to mock during execution, potentially leading to the utilization of Jinja2 templates for remote privilege escalation and the execution of arbitrary code as the root user on the build server.

An authentication bypass flaw was found in GRUB due to the way that GRUB uses the UUID of a device to search for the configuration file that contains the password hash for the GRUB password protection feature. An attacker capable of attaching an external drive such as a USB stick containing a file system with a duplicate UUID (the same as in the "/boot/" file system) can bypass the GRUB password protection feature on UEFI systems, which enumerate removable drives before non-removable ones. This issue was introduced in a downstream patch in Red Hat's version of grub2 and does not affect the upstream package.

A flaw was found in the blkgs destruction path in block/blk-cgroup.c in the Linux kernel, leading to a cgroup blkio memory leakage problem. When a cgroup is being destroyed, cgroup_rstat_flush() is only called at css_release_work_fn(), which is called when the blkcg reference count reaches 0. This circular dependency will prevent blkcg and some blkgs from being freed after they are made offline. This issue may allow an attacker with a local access to cause system instability, such as an out of memory error.

Jan 10, 2024A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions of IPA.CVE-2023-5455 · Other software · Red Hat · reported by Red HatMedium 6.5
A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions of IPA. This flaw allows an attacker to trick the user into submitting a request that could perform actions as the user, resulting in a loss of confidentiality and system integrity. During community penetration testing it was found that for certain HTTP end-points FreeIPA does not ensure CSRF protection. Due to implementation details one cannot use this flaw for reflection of a cookie representing already logged-in user. An attacker would always have to go through a new authentication attempt.

Jan 4, 2024A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel.CVE-2023-6270 · Other software · Red Hat · reported by Red HatHigh 7
A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on `struct net_device`, and a use-after-free can be triggered by racing between the free on the struct and the access through the `skbtxq` global queue. This could lead to a denial of service condition or potential code execution.

Jan 3, 2024A use-after-free flaw was found in PackageKitd.CVE-2024-0217 · Other software · Red Hat · reported by Red HatLow 3.3
A use-after-free flaw was found in PackageKitd. In some conditions, the order of cleanup mechanics for a transaction could be impacted. As a result, some memory access could occur on memory regions that were previously freed. Once freed, a memory region can be reused for other allocations and any previously stored data in this memory region is considered lost.

A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a use-after-free issue on an NFT_CHAIN object or NFT_OBJECT object, allowing a local unprivileged user with CAP_NET_ADMIN capability to escalate their privileges on the system.

Jan 2, 2024A stack based buffer overflow was found in the virtio-net device of QEMU.CVE-2023-6693 · Other software · Red Hat · reported by Red HatMedium 4.9
A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
