CVE-2025-22083

The CVE-2025-22083 issue affects Linux kernel vhost-scsi handling: multiple vhost_scsi_set_endpoint calls without an intervening vhost_scsi_clear_endpoint can trigger three bugs in the vs_tpg lifecycle. 1) Use-after-free when no tpgs are found after a second call, due to freed vs->vs_tpg backi...

CVE-2025-22077

CVE-2025-22077 concerns Linux kernel CIFS SMB client TCP timers deadlock after rmmod. The advisory notes the patch that attempted to fix a NULL dereference in LOCKDEP via a CIFS netns reference was reverted, reviving a kernel TCP socket timer lifecycle mismatch. This reversion can cause FIN_WAIT_...

CVE-2025-22072

CVE-2025-22072 affects the Linux kernel spufs component, addressing leaks in gang directory lifetimes. The issue: creating a gang returns an opened gang directory that should be removed on close, but if a context belonging to that gang remains alive, removal could fail, causing a leak. The fix de...

CVE-2025-22025

CVE-2025-22025: In the Linux kernel NFS server (nfsd), if nfsd4_run_cb fails while queuing a dl_recall, the incremented dl_stid reference is not decremented, causing a potential dl_stid leak. The issue is addressed by checking the result of nfsd4_run_cb and, on failure, calling nfs4_put_stid to p...

kernel: irqchip/gic-v4: Don't allow a VMOVP on a dying VPE

A flaw was found in the Linux kernel. A race condition exists in the irqchip/gic-v4 component, where a local user can force a change of affinity for a Virtual Processing Element VPE after it has been unmapped. This occurs because the corresponding doorbell interrupt remains visible, creating a...
