CVE-2026-63793

In the Linux kernel, the following vulnerability has been resolved: ntfs: serialize volume label accesses Protect vol-volumelabel with a mutex and snaphost the label before copytouser. This prevent a use-after-free when FSIOCSETFSLABEL replaces the vol-volumelabel and FSIOCGETTSLABEL reads it...

CVE-2026-63825 gcov: use atomic counter updates to fix concurrent access crashes

In the Linux kernel, the following vulnerability has been resolved: gcov: use atomic counter updates to fix concurrent access crashes GCC's GCOV instrumentation can merge global branch counters with loop induction variables as an optimization. In inflatefast, the inner copy loops get transformed ...

CVE-2026-63825

CVE-2026-63825 describes a Linux kernel issue where GCC GCOV instrumentation could merge global counters with loop induction variables, causing inconsistent values and an out-of-bounds write during IPComp processing when inflate_fast() runs on multiple CPUs. The root cause is in the GCOV counter ...

CVE-2026-63793

CVE-2026-63793 affects the Linux kernel’s NTFS handling. The issue arises from unsafe concurrent access to vol->volume_label during FS_IOC_SETFSLABEL and FS_IOC_GETTSLABEL, which could lead to a use-after-free. The patch inserts a mutex to guard the volume_label and snapshots the label before ...

CVE-2026-53385

CVE-2026-53385 relates to a Linux kernel issue in vc_screen where a race in vcs_write() can yield a stale vc_data after the console_lock is dropped and re-acquired. If the vc has been deallocated in the interim, a subsequent call to vcs_scr_updated() uses a NULL vc, causing a null-pointer derefer...
