CVE-2026-31703

A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the inodeswitchwbsworkfn function, part of the kernel's writeback subsystem. This issue arises when a work item remains active after its associated memory object wb has been released, leading to system instability. An...

CVE-2026-43053

A flaw was found in the Linux kernel's XFS filesystem. During the inactivation of inodes with extended attributes, a specific timing window exists where a log shutdown can occur after some data blocks are invalidated but before the attribute map is fully truncated. This can lead to inconsistencie...

In the Linux kernel, the following vulnerability has been resolved: f2fs: fix UAF caused by decrementing sbi-nrpages in f2fswriteendio The xfstests case "generic/107" and syzbot have both reported a NULL pointer dereference. The concurrent scenario that triggers the panic is as follows:...

CVE-2026-31715

In Linux kernel (f2fs), CVE-2026-31715 is a use-after-free triggered by decrementing sbi->nr_pages[] during F2FS_WB_CP_DATA handling. The root cause is that f2fs_put_super() calls iput(sbi->node_inode) and NULLs the node_inode after the counter reaches zero, allowing f2fs_in_warm_node_list(...
