Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: corrected the incorrect validation of the numaces field in smbacl. parsedcal now validates numaces to allocate an array of posixacestatearray. If numaces is greater than ULONGMAX / sizeofstruct smbace++, it results in a...

CVE-2025-21994

CVE-2025-21994 in the Linux kernel ksmbd component fixes an incorrect validation of the num_aces field in smb_acl. The code previously validated num_aces against ULONG_MAX / sizeof(struct smb_ace *), allowing potential allocation of an array of size ULONG_MAX. The correct check uses the actual nu...
