Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: drm/shmem-helper: Removed the erroneous “put” operation in the error path. The drmgemshmemmmap function does not handle this reference properly, resulting in the GEM object being freed prematurely, leading to a “use-after-free...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fixed the mpolnew leak in sharedpolicyreplace. If mpolnew is allocated but not used during the restart loop, mpolnew will be freed via mpolput before returning to the caller. However, refcnt has not been initialized...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rtc: gamecube: Fixed a refcount leak in gamecubertcreadoffsetfromsram. The offindcompatiblenode function returns a node pointer whose refcount is incremented. We should use ofnodeput on it after processing. Also, add the missing...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: A possible reference count leak in smb2open has been fixed. The reference count of ACLs will cause a leak when memory allocation fails. This issue has been addressed by adding the missing posixaclrelease function...
