SUSE CVE-2026-63803

In the Linux kernel, the following vulnerability has been resolved: hdlcppp: sync per-proto timers before freeing hdlc state Each PPP control protocol LCP/IPCP/IPV6CP embedded in struct ppp registers a timer via timersetup. That struct ppp is the hdlc-state allocation, which detachhdlcprotocol...

CVE-2026-63974

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: Set HCICMDDRAINWORKQUEUE during device close Since hcidevclosesync can now be called during the reset path, we should also set HCICMDDRAINWORKQUEUE. This avoids queuing timeouts while the hdev workqueue is bei...

CVE-2026-64164

The CVE entry concerns the Linux kernel Btrfs tracepoints: btrfs_sync_file() is invoked in an atomic context, and its use of dput() (due to dget_parent()) can sleep, causing a kernel splat. The fix, as described in the linked references, is to stop using dget_parent() and dput() and instead acces...

CVE-2026-64156 netfs, afs: Fix write skipping in dir/link writepages

In the Linux kernel, the following vulnerability has been resolved: netfs, afs: Fix write skipping in dir/link writepages Fix netfswritesingle and afssinglewritepages to better handle a write that would be skipped due to lock contention and WBSYNCNONE by returning 1 from netfswritesingle if it...

CVE-2026-64112 rbd: eliminate a race in lock_dwork draining on unmap

In the Linux kernel, the following vulnerability has been resolved: rbd: eliminate a race in lockdwork draining on unmap Given how rbdlockaddrequest and rbdimgexclusivelock are written, lockdwork may be requeued more than it's actually needed: for example in case a new I/O request comes in while ...

CVE-2026-64099 drm/v3d: Fix use-after-free of CPU job query arrays on error path

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Fix use-after-free of CPU job query arrays on error path The CPU job ioctl's fail label calls kvfree on cpujob's timestamp and performance query arrays after v3djobcleanup, which drops the job's last reference and frees...

CVE-2026-64093 batman-adv: tp_meter: directly shut down timer on cleanup

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tpmeter: directly shut down timer on cleanup batadvtpsendercleanup was calling timerdeletesync followed by timerdelete to guard against the timer handler re-arming itself between the two calls. This double-deletion ha...

CVE-2026-64093

The CVE concerns batman-adv (Linux kernel) where tp_meter cleanup caused a potential re-arm of a timer due to two-step deletion. batadv_tp_sender_cleanup() called timer_delete_sync() followed by timer_delete(); the fix replaces both calls with a single timer_shutdown_sync() that waits for any run...

CVE-2026-63803

The CVE-2026-63803 has concrete technical details in the Linux kernel: hdlc_ppp timers for PPP LCP/IPCP/IPV6CP in struct ppp are not synchronized on teardown due to a missing .detach callback, causing a use-after-free when a ppp_timer dereferences freed memory. The fix adds a detach helper that c...
