Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: xfrm: State: fixed an out-of-bounds read during lookup. Lookup and resizing can operate in parallel. The xfrmstatehashgeneration seqlock ensures a retry mechanism, but the hash functions may encounter a hmask value that is too...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: In the TCP layer, the secpath process is now executed simultaneously with the current execution of the dst process. Xiumei reported encountering a warning in xfrm6tunnelnetexit while running tests that involve creating a pair of...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: xfrm: delete intermediate secpath entry in packet offload mode Packets handled by hardware have added secpath as a way to inform XFRM core code that this path was already handled. That secpath is not needed at all after policy is...

PT-2025-34436

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: A flaw exists in the Linux kernel related to the xfrm state management. Specifically, the state ptrs variable is not initialized early enough within the xfrm state find function. This...

CVE-2020-9087

Taurus-AL00A version 10.0.0.1C00E1R1P1 has an out-of-bounds read vulnerability in XFRM module. An authenticated, local attacker may perform a specific operation to exploit this vulnerability. Due to insufficient validation of the parameters, which may be exploited to cause information leak...

CVE-2019-14053

When attempting to create a new XFRM policy, a stack out-of-bounds read will occur if the user provides a template where the mode is set to a value that does not resolve to a valid XFRM mode in Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer...

kernel: bonding: fix xfrm real_dev null pointer dereference

In the Linux kernel, the following vulnerability has been resolved: bonding: fix xfrm realdev null pointer dereference We shouldn't set realdev to NULL because packets can be in transit and xfrm might call xdodevoffloadok in parallel. All callbacks assume realdev is set. Example trace: kernel: BU...

kernel: net: Fix icmp host relookup triggering ip_rt_bug

A denial of service vulnerability was found in the Linux kernel. icmproutelookup creates input routes for locally generated packets during xfrm relookup ICMP traffic. Then it will set the input route dst-out = iprtbug to skb for DESTUNREACH, leading to loss of availability of the system...
