Description
In the Linux kernel, the following vulnerability has been resolved:
rxrpc, afs: Fix missing error pointer check after rxrpc_kernel_lookup_peer()
rxrpc_kernel_lookup_peer() can also return error pointers in addition to
NULL, so just checking for NULL is not sufficient.
Fix this by:
(1) Changing rxrpc_kernel_lookup_peer() to return -ENOMEM rather than NULL
on allocation failure.
(2) Making the callers in afs use IS_ERR() and PTR_ERR() to pass on the
error code returned.
Affected configurations
• linux linux kernel (>= 6.7.3 < 6.8)
• linux linux kernel (>= 6.8 < 6.18.19)
• linux linux kernel (>= 6.19 < 6.19.9)
• linux linux kernel 7.0
