CVE-2026-64391

A flaw was found in ksmbd, the in-kernel Server Message Block SMB daemon. This vulnerability allows a remote attacker to bypass security restrictions by incorrectly handling credentials for Alternate Data Streams ADS input/output I/O operations. Instead of using the credentials established when t...

In the Linux kernel, the following vulnerability has been resolved: bpf: Drop tasktoinode and inetconnestablished from lsm sleepable hooks bpflsmtasktoinode is called under rcureadlock and bpflsminetconnestablished is called from softirq context, so neither hook can be used by sleepable LSM...

SUSE CVE-2026-64111

In the Linux kernel, the following vulnerability has been resolved: lsm: hold credguardmutex for lsmsetselfattr Just as procpidattrwrite already does before calling the LSM hook. This only matters for SELinux and AppArmor which check whether the process is being ptraced and if so, whether to allo...

CVE-2026-64111

A flaw was found in the Linux kernel's Security Module LSM. A local attacker could exploit this vulnerability by leveraging an improper handling of a credential guard mutex in the lsmsetselfattr function. This oversight may allow the attacker to bypass security restrictions enforced by modules su...

CVE-2026-64192

CVE-2026-64192 affects the Linux kernel (BPF inode storage maps). When CONFIG_BPF_LSM=y and the BPF LSM is not enabled at boot, lsm_prepare() doesn’t run, so the BPF LSM blob size (lbs_inode) remains at the compiled default (8 bytes) instead of a larger offset. This lets a privileged user create/...
