An update of the linux package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - netfilter: nf_conntrack: fix crash due to removal of uninitialised entry A crash in conntrack was reported     while trying to unlink the conntrack entry from the hash bucket list: [exception RIP:
    __nf_ct_delete_from_lists+172] [..] #7 [ff539b5a2b043aa0] nf_ct_delete at ffffffffc124d421 [nf_conntrack]     #8 [ff539b5a2b043ad0] nf_ct_gc_expired at ffffffffc124d999 [nf_conntrack] #9 [ff539b5a2b043ae0]
    __nf_conntrack_find_get at ffffffffc124efbc [nf_conntrack] [..] The nf_conn struct is marked as allocated     from slab but appears to be in a partially initialised state: ct hlist pointer is garbage; looks like the     ct hash value (hence crash). ct->status is equal to IPS_CONFIRMED|IPS_DYING, which is expected ct->timeout     is 30000 (=30s), which is unexpected. Everything else looks like normal udp conntrack entry. If we ignore     ct->status and pretend its 0, the entry matches those that are newly allocated but not yet inserted into     the hash: - ct hlist pointers are overloaded and store/cache the raw tuple hash - ct->timeout matches the     relative time expected for a new udp flow rather than the absolute 'jiffies' value. If it were not for the     presence of IPS_CONFIRMED, __nf_conntrack_find_get() would have skipped the entry. Theory is that we did     hit following race: cpu x cpu y cpu z found entry E found entry E E is expired <preemption> nf_ct_delete()     return E to rcu slab init_conntrack E is re-inited, ct->status set to 0 reply tuplehash hnnode.pprev     stores hash value. cpu y found E right before it was deleted on cpu x. E is now re-inited on cpu z. cpu y     was preempted before checking for expiry and/or confirm bit. ->refcnt set to 1 E now owned by skb
    ->timeout set to 30000 If cpu y were to resume now, it would observe E as expired but would skip E due to     missing CONFIRMED bit. nf_conntrack_confirm gets called sets: ct->status |= CONFIRMED This is wrong: E is     not yet added to hashtable. cpu y resumes, it observes E as expired but CONFIRMED: <resumes>     nf_ct_expired() -> yes (ct->timeout is 30s) confirmed bit set. cpu y will try to delete E from the     hashtable: nf_ct_delete() -> set DYING bit __nf_ct_delete_from_lists Even this scenario doesn't guarantee     a crash: cpu z still holds the table bucket lock(s) so y blocks: wait for spinlock held by z CONFIRMED is     set but there is no guarantee ct will be added to hash: chaintoolong or clash resolution logic both     skip the insert step. reply hnnode.pprev still stores the hash value. unlocks spinlock return NF_DROP     <unblocks, then crashes on hlist_nulls_del_rcu pprev> In case CPU z does insert the entry into the     hashtable, cpu y will unlink E again right away but no crash occurs. Without 'cpu y' race, 'garbage' hlist     is of no consequence: ct refcnt remains at 1, eventually skb will be free'd and E gets destroyed via:
    nf_conntrack_put -> nf_conntrack_destroy -> nf_ct_destroy. To resolve this, move the IPS_CONFIRMED     assignment after the table insertion but before the unlock. Pablo points out that the confirm-bit-store     could be reordered to happen before hlist add resp. the timeout fixup, so switch to set_bit and     before_atomic memory barrier to prevent this. It doesn't matter if other CPUs can observe a newly inserted     entry right before the CONFIRMED bit was set: Such event cannot be distinguished from above E is the old     incarnation case: the entry will be skipped. Also change nf_ct_should_gc() to first check the confirmed     bit. The gc sequence is: 1. Check if entry has expired, if not skip to next entry 2. Obtain a reference to     the expired entry. 3. Call nf_ct_should_gc() to double-check step 1. nf_ct_should_gc() is thus called only     for entries that already failed an expiry check. After this patch, once the confirmed bit check pas

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 6.1.147-1.

    We recommend that you upgrade your linux packages.
