CVE-2026-23350

CVE-2026-23350 is a Linux kernel vulnerability in the drm/xe/queue path. The issue arises when an exec queue creation fails and is not properly finalized, leaving a damaged queue in exec_queue_lookup which can cause an invalid memory reference. The fix adds a finalization call (fini) for each que...

CVE-2026-23337

The CVE-2026-23337 entry concerns the Linux kernel, specifically the pinconf-generic driver in the pinctrl subsystem. The root cause is a memory leak in pinconf_generic_parse_dt_config() when parse_dt_cfg() fails and exits early, bypassing cleanup. The resulting leak is of the cfg buffer. The fix...

CVE-2026-23334

The CVE-2026-23334 issue affects the Linux kernel in the can: usb: f81604 path, where interrupt URBs of incorrect length could be misinterpreted as valid data. The vulnerability is addressed by upstream kernel fixes, and Mageia advisories reference kernel version 6.6.130 as the fixing baseline, w...

CVE-2026-23324 can: usb: etas_es58x: correctly anchor the urb in the read bulk callback

In the Linux kernel, the following vulnerability has been resolved: can: usb: etases58x: correctly anchor the urb in the read bulk callback When submitting an urb, that is using the anchor pattern, it needs to be anchored before submitting it otherwise it could be leaked if usbkillanchoredurbs is...

CVE-2026-23305

The CVE-2026-23305 entry concerns a Linux kernel issue in accel/rocket where unwinding in rocket_probe’s error path was incorrect. If rocket_core_init() fails (e.g., due to EPROBE_DEFER), the kernel must unwind by decrementing the incremented counter and, if it’s the first core failed to probe, c...

CVE-2026-23297 nfsd: Fix cred ref leak in nfsd_nl_threads_set_doit().

In the Linux kernel, the following vulnerability has been resolved: nfsd: Fix cred ref leak in nfsdnlthreadssetdoit. syzbot reported memory leak of struct cred. 0 nfsdnlthreadssetdoit passes getcurrentcred to nfsdsvc, but putcred is not called after that. The cred is finally passed down to...
