In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - get rid of alg_memory_allocated
alg_memory_allocated does not seem to be really used.
alg_proto does have a .memory_allocated field, but no
corresponding .sysctl_mem.
This means sk_has_account() returns true, but all sk_prot_mem_limits()
users will trigger a NULL dereference [1].
THis was not a problem until SO_RESERVE_MEM addition.
