CVE-2026-89603

CVE-2026-89603 is a race condition in the Linux kernel's syscall_trace_enter() that allows seccomp filter bypass via ptrace. When a thread is stopped for ptrace, another thread can install a seccomp filter with SECCOMP_FILTER_FLAG_TSYNC; however, syscall_trace_enter() evaluates a cached 'work' va...

CVE-2026-89602

CVE-2026-89602 affects the erofs (Enhanced Read-Only File System) component of the Linux kernel . When resizing global buffers, a failed partial resize leaves a retry path that either returns a spurious -ENOMEM (same-size retry) or allocates a temporary pointer array too small for the existing po...

CVE-2026-89601

This vulnerability affects the Linux kernel ext2 filesystem in the ext2_setsize() and ext2_xattr_set2() functions. The root cause is that for IS_SYNC inodes , sync_inode_metadata() is called without first marking the inode dirty; since that function only operates on already-dirty inodes, inode up...

CVE-2026-89600

CVE-2026-89600 is a use-after-free vulnerability in the Linux kernel's fanotify subsystem . The root cause: fsnotify_pre_content() builds a file_range on the triggering task's stack, and fanotify_alloc_perm_event() stores a pointer to range.pos in a heap-allocated permission event. If a signal in...
