In the Linux kernel, the following vulnerabilities have been resolved: cifs: fixed an oops during encryption When running xfstests against Azure, the following oops occurred on an arm64 system: Unable to handle kernel writes to read-only memory at virtual address ffff0001221cf000 Mem abort info:...

Astra Linux - уязвимость в linux-5.15

A use-after-free flaw was discovered in the smb2isstatusiotimeout function in CIFS within the Linux kernel. After CIFS transfers response data via a system call, there are still local variables pointing to the memory region. If the system call frees those pointers faster than CIFS uses them, CIFS...

Astra Linux - уязвимость в linux-5.15

A issue was discovered in the Linux kernel before version 6.3.8. In the file fs/smb/server/connection.c of ksmbd, the relationship between the length field of the NetBIOS header and the sizes of the SMB headers is not validated, as handled through the pdudsize function in ksmbdconnhandlerloop. Th...
