xorg: xwayland: X.Org X server: Information exposure and denial of service via out-of-bounds memory access

A flaw was found in the X.Org X server's XKB key types request validation. A local attacker could send a specially crafted request to the X server, leading to an out-of-bounds memory access vulnerability. This could result in the disclosure of sensitive information or cause the server to crash,...

xorg: xwayland: X.Org X server: Denial of Service via integer underflow in XKB compatibility map handling

A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of servi...

xorg: xwayland: X.Org X server: Use-after-free vulnerability leads to server crash and potential memory corruption

A flaw was found in the X.Org X server. This use-after-free vulnerability occurs in the XSYNC fence triggering logic, specifically within the miSyncTriggerFence function. An attacker with access to the X11 server can exploit this without user interaction, leading to a server crash and potentially...

CVE-2026-46175

Summary of CVE-2026-46175 (f2fs FGGC issue) : In the Linux kernel’s f2fs filesystem, Foreground Garbage Collection (FGGC) of node blocks could leave the fsync and dentry marks uncleared, causing fsck to misinterpret migrated data as fsync-written. The root cause is that the marks were not cleared...

CVE-2026-46160

CVE-2026-46160 concerns the Linux kernel’s Btrfs filesystem: when removing a directory, last_unlink_trans is not updated, which can lead to incorrect fsync behavior if a directory with an open file descriptor is fsynced after removal. This can cause log replay during mount to fail with -EIO, pote...
