CVE-2026-64040

In the Linux kernel, the following vulnerability has been resolved: cachefiles: Fix error return when vfsmkdir fails When vfsmkdir fails, the error code is not extracted from the returned error pointer. This causes mkdirerror to be reached with ret=0, which leads to returning ERRPTR0 NULL instead...

CVE-2026-64155

CVE-2026-64155 is a memory leak in the ath11k WiFi driver in the Linux kernel. Two error paths in WMI WOW (Wake-on-Wireless) calls directly returned the result of ath11k_wmi_cmd_send() without checking the return value, causing the skb to not be freed on error. This results in a high availability...

CVE-2026-64148

In the Linux kernel, the following vulnerability has been resolved: pdscore: fix error handling in pdscdevcmdwait Fix two cases where pdscdevcmdwait returns stale success from the completion register instead of an error: 1. FW crash: If firmware stops running, the wait loop breaks early with...

CVE-2026-64147

The pds_core kernel driver leaks a dentry reference (missing dput()) on every firmware reset recovery, and when CONFIG_DEBUG_FS is disabled, debugfs_lookup() returns ERR_PTR(-ENODEV) rather than NULL, which the existing check passes, causing a crash. Red Hat confirms this can lead to denial of se...
