Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xfrm: Update ipcompscratches with NULL when freed Currently, if ipcompallocscratches fails to allocate memory, ipcompscratches holds an obsolete address. Therefore, when we try to free the percpu scratches using...

The vulnerability of the ipcomp_post_acomp() function in the net/xfrm/xfrm_ipcomp.c module, which is part of the networking functions of the Linux kernel, allows a hacker to cause a service failure.

The vulnerability of the ipcomppostacomp function in the net/xfrm/xfrmipcomp.c module, which is part of the networking functions of the Linux kernel, relates to the failure to release resources after their useful life has expired. Exploiting this vulnerability could allow a remote attacker to cau...
