It was discovered that the HugeTLB file system component of the Linux Kernel contained a NULL pointer dereference vulnerability. A privileged attacker could possibly use this to to cause a denial of service. CVE-2024-0841 Several security issues were discovered in the Linux kernel. An attacker...

PT-2024-33809

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue concerns the ext4 filesystem in the Linux kernel. When mounting the ext4 filesystem, if the default hash version is set to DX HASH SIPHASH but the casefold feature is not set...

kernel: ext4: fix deadlock due to mbcache entry corruption

A deadlock vulnerability was found in the ext4 filesystem in the Linux kernel. When manipulating extended attribute xattr blocks, a race condition in non-atomic bitfield updates can cause the mbcache entry state to become corrupted. This leads to an infinite loop in ext4xattrblockset where the co...

kernel: ext4: fix uninititialized value in 'ext4_evict_inode'

An uninitialized variable flaw was found in the Linux kernel's ext4 filesystem in the inode eviction path. A local user can trigger this issue by creating filesystem operations that cause inode allocation to fail before the iflags field is initialized, followed by inode cleanup that attempts to...

kernel: ext4: fix bug_on in __es_tree_search caused by bad boot loader inode

A flaw was identified in the ext4 filesystem implementation in the Linux kernel where a malformed or improperly initialized boot loader inode could trigger a BUGON condition inside the estreesearch function. This occurs when the inode’s mode imode is an unexpected type and the code does not...

USN-6777-3 linux-gcp vulnerabilities

Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service system crash. CVE-2023-47233 Several...

CVE-2021-47342

In the Linux kernel, the following vulnerability has been resolved: ext4: fix possible UAF when remounting r/o a mmp-protected file system After commit 618f003199c6 "ext4: fix memory leak in ext4fillsuper", after the file system is remounted read-only, there is a race where the kmmpd thread can...

USN-6778-1 linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities

Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service system crash. CVE-2023-47233 Several...

USN-6767-2 linux-bluefield vulnerabilities

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-bounds read vulnerability. An attacker could use this to possibly cause a denial of service system crash. CVE-2024-23849 Several security issues were discovered in the Linux kernel. An attacker...

SUSE-SU-2024:1491-1 Security update for the Linux Kernel RT (Live Patch 0 for SLE 15 SP5)

This update for the Linux Kernel 5.14.21-15050011 fixes one issue. The following security issue was fixed: - CVE-2024-0775: Fixed a use-after-free flaw was found in the ext4remount in fs/ext4/super.c in ext4 bsc1219079...

kernel: ext4: fix use-after-free in ext4_orphan_cleanup

A use-after-free vulnerability was found in the ext4 filesystem's orphan inode cleanup routine in the Linux kernel. When ext4inodeattachjinode fails with -ENOMEM during orphan cleanup at mount time, the error is not properly propagated. The inode is freed via iput, but the orphan list still...

kernel: ext4: fix invalid free tracking in ext4_xattr_move_to_block()

A memory management flaw was found in the Linux kernel's ext4 filesystem extended attribute handling. In ext4xattrmovetoblock, when moving an extended attribute value to an external block, the code checks entry-evalueinum to determine if the buffer was allocated via kvmalloc. However, at cleanup...

kernel: ext4: avoid deadlock in fs reclaim with page writeback

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid deadlock in fs reclaim with page writeback Ext4 has a filesystem wide lock protecting ext4writepages calls to avoid races with switching of journalled data flag or inode format. This lock can however cause a deadlock...

CVE-2024-26774 ext4: avoid dividing by 0 in mb_update_avg_fragment_size() when block bitmap corrupt

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid dividing by 0 in mbupdateavgfragmentsize when block bitmap corrupt Determine if bbfragments is 0 instead of determining bbfree to eliminate the risk of dividing by zero when the block bitmap is corrupted...

CVE-2024-26704 ext4: fix double-free of blocks due to wrong extents moved_len

In the Linux kernel, the following vulnerability has been resolved: ext4: fix double-free of blocks due to wrong extents movedlen In ext4moveextents, movedlen is only updated when all moves are successfully executed, and only discards originode and donorinode preallocations when movedlen is not...
