UBUNTU-CVE-2026-46050

In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix deadlock with check operation and nowait requests When an array check is running it will raise the barrier at which point normal requests will become blocked and increment the nrpending value to signal there is wor...

EUVD-2026-32460

In the Linux kernel, the following vulnerability has been resolved: erofs: fix the out-of-bounds nameoff handling for trailing dirents Currently we already have boundary-checks for nameoffs, but the trailing dirents are special since the namelens are calculated with strnlen with unchecked nameoff...

CVE-2026-46078

Summary: CVE-2026-46078 affects the Linux kernel EROFS filesystem, where trailing dirents can trigger an out-of-bounds read due to incorrect nameoff handling. The root cause is that namelen calculations for trailing dirents use strnlen with unchecked nameoffs, allowing underflow when nameoff >...

CVE-2026-46050

CVE-2026-46050 : In the Linux kernel, the md/raid10 deadlock arises when an array check runs concurrently with NOWAIT IO. The check path raises a barrier and increments nr_pending, while NOWAIT requests return immediately and do not increment nr_pending, leading to a mismatch. Upstream changes (r...

CVE-2026-45915

CVE-2026-45915 — FAT filesystem rmdir link-count underflow (Linux kernel) Root cause: When FAT images are corrupted, a directory inode’s i_nlink can be incorrect (e.g., 2) while subdirectories exist, causing rmdir to call drop_nlink(dir) unconditionally and potentially drive i_nlink to 0, trigger...

CVE-2026-45915

In the Linux kernel, the following vulnerability has been resolved: fat: avoid parent link count underflow in rmdir Corrupted FAT images can leave a directory inode with an incorrect inlink e.g. 2 even though subdirectories exist. rmdir then unconditionally calls dropnlinkdir and can drive inlink...

CVE-2026-45910

The CVE-2026-45910 issue affects the Linux kernel RDMA/rxe driver, caused by a race between retransmit_timer() and rxe_destroy_qp that can drop a Queue Pair (QP) reference count to zero during timer handling. Public documents describe a use-after-free risk and refcount underflow in affected flows...
