The vulnerability of the xfrm_alloc_spi() function in the net/xfrm/xfrm_state.c module, which is part of the Linux kernel’s networking functions, allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the xfrmallocspi function in the net/xfrm/xfrmstate.c module, which implements networking functions in the Linux kernel, is related to insufficient checks for data uniqueness during searches. Exploiting this vulnerability could allow an attacker to compromise the...

CVE-2025-39965

The CVE-2025-39965 vulnerability affects the Linux kernel XFRM stack: xfrm_alloc_spi may create states with SPI set to 0 (meaning “no SPI assigned”) due to the behavior change from commit 94f39804d891, and __xfrm_state_delete fails to remove those states from the byspi list. This leads to a use-a...

CVE-2025-39965: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: xfrm: xfrmallocspi shouldn't use 0 as SPI x-id.spi == 0 means "no SPI assigned", but since commit 94f39804d891 "xfrm: Duplicate SPI Handling", we now create states and add them to the byspi list with this value. xfrmstatedelete...

CVE-2025-39797: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: xfrm: Duplicate SPI Handling The issue originates when Strongswan initiates an XFRMMSGALLOCSPI Netlink message, which triggers the kernel function xfrmallocspi. This function is expected to ensure uniqueness of the Security...
