CVE-2024-33847
The CVE-2024-33847 issue concerns the Linux kernel F2FS file system where compressed inodes could be corrupted after unaligned or partial truncation. The vulnerability arises when a released compress inode with reserved blocks undergoes truncation that changes valid_block_count without updating i...

CVE-2024-38604
In the Linux kernel, the following vulnerability has been resolved: block: refine the EOF check in blkdeviomapbegin blkdeviomapbegin rounds down the offset to the logical block size before stashing it in iomap-offset and checking that it still is inside the inode size. Check the isize check to th...
UBUNTU-CVE-2022-48712
In the Linux kernel, the following vulnerability has been resolved: ext4: fix error handling in ext4fcrecordmodifiedinode Current code does not fully takes care of krealloc error case, which could lead to silent memory corruption or a kernel bug. This patch fixes that. Also it cleans up some...
CVE-2021-47585
CVE-2021-47585 concerns a memory leak in the Linux kernel's btrfs __add_inode_ref path. The issue arises from allocating victim_name with kmalloc at two points (lines 1104 and 1169) and returning from the function without freeing the previously allocated memory when backref_in_log() returns an er...
