In the Linux kernel, the following vulnerability has been resolved: ACPI: Processor: Fixed NULL-pointer dereferencing in acpiprocessorerratapiix4 In acpiprocessorerratapiix4, the pointer dev is first assigned an IDE device, and then reassigned as an ISA device: dev = pcigetsubsys...,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: xprtrdma: fixed pointer dereferencing in error cases of rpcrdmaepcreate. If there are failures, we must not leave non-NULL pointers with error values. Otherwise, rpcrdmaepDestroy will be confused and try to free those pointers...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in the ksmbd component of the Linux kernel, a high-performance in-kernel SMB server. The specific flaw occurs during the handling of SMB2LOGOFF commands. The issue arises from the lack of proper validation of a pointer before accessing it. An attacker can exploit this...
