In the Linux kernel, the following vulnerability has been resolved:
net/sched: act_ct: fix skb leak and crash on ooo frags
act_ct adds skb->users before defragmentation. If frags arrive in order,
the last frag's reference is reset in:
inet_frag_reasm_prepare
skb_morph
which is not straightforward.
However when frags arrive out of order, nobody unref the last frag, and
all frags are leaked. The situation is even worse, as initiating packet
capture can lead to a crash[0] when skb has been cloned and shared at the
same time.
Fix the issue by removing skb_get() before defragmentation. act_ct
returns TC_ACT_CONSUMED when defrag failed or in progress.

CVE-2023-52610 [MEDIUM] CWE-402 kernel: net/sched: act_ct: fix skb leak and crash on ooo frags
kernel: net/sched: act_ct: fix skb leak and crash on ooo frags
In the Linux kernel, the following vulnerability has been resolved:
net/sched: act_ct: fix skb leak and crash on ooo frags
act_ct adds skb->users before defragmentation. If frags arrive in order,
the last frag's reference is reset in:
inet_frag_reasm_prepare
skb_morph
which is not straightforward.
However when frags arrive out of order, nobody unref the last frag, and
all frags are leaked. The situation is even worse, as initiating packet
capture can lead to a crash[0] when skb has been cloned and shared at the
same time.
Fix the issue by removing skb_get() before defragmentation. act_ct
returns TC_ACT_CONSUMED when defrag failed or in progress.
