CVE-2022-50569

Summary of CVE-2022-50569 (Linux kernel xfrm/ipcomp_scratches): The vulnerability arises when ipcomp_alloc_scratches() fails to allocate per-CPU scratches, leaving ipcomp_scratches with an obsolete address. During ipcomp_free_scratches(), the code frees per-CPU scratch space by iterating CPUs and...

The vulnerability of the xfrm_alloc_spi() function in the net/xfrm/xfrm_state.c module of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the xfrmallocspi function in the net/xfrm/xfrmstate.c module of the Linux operating system is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to cause a service failure...
