| In the Linux kernel, the following vulnerability has been resolved:
fuse-uring: fix moving cancelled entry to ent_in_userspace list
fuse_uring_cancel() moves entries that are available (these have no reqs
attached) to the ent_in_userspace list. ent_list_request_expired()
checks the first entry on ent_in_userspace and dereferences
ent->fuse_req unconditionally, which will crash on a cancelled entry
that was moved to this list.
Fix this by freeing the entry and dropping queue_refs directly in
fuse_uring_cancel(). This is safe because cancel is the cancel handler
itself - after io_uring_cmd_done(), no more cancels will be dispatched
for this command, and teardown serializes with cancel via queue->lock.
Since cancel now decrements queue_refs, fuse_uring_abort() must no
longer gate fuse_uring_abort_end_requests() on queue_refs > 0, as
cancelled entries may have already dropped queue_refs while requests are
still queued. Remove the gate so abort always flushes requests and stops
queues. |
| A denial of service vulnerability could be triggered by sending specially crafted HTTP requests to server function endpoints, this could lead to server crashes, out-of-memory exceptions or excessive CPU usage; affecting the following packages: react-server-dom-webpack, react-server-dom-parcel, react-server-dom-turbopack (versions 19.0.0 through 19.0.5, 19.1.0 through 19.1.6, and 19.2.0 through 19.2.5). |
| In the Linux kernel, the following vulnerability has been resolved:
fuse: avoid 32-bit prune notification count wrap
FUSE_NOTIFY_PRUNE validates the nodeid payload length with:
size - sizeof(outarg) != outarg.count * sizeof(u64)
On 32-bit kernels, size_t is also 32 bits, so the daemon-controlled
count multiplication can wrap. A prune notification with count
0x20000000 and no nodeid payload passes the check, enters the copy
loop, and asks the device copy path to read nodeids that are not
present in the userspace write buffer. In QEMU this reaches the
fuse_copy_fill() BUG_ON(!err) path.
Validate the payload length with array_size() instead. That accepts
exactly the same valid messages, but avoids wrapping arithmetic before
the copy loop consumes the count. |
| In the Linux kernel, the following vulnerability has been resolved:
lsm: hold cred_guard_mutex for lsm_set_self_attr()
Just as proc_pid_attr_write() already does before calling the LSM
hook. This only matters for SELinux and AppArmor which check
whether the process is being ptraced and if so, whether to
allow the transition. |
| In the Linux kernel, the following vulnerability has been resolved:
ipv6: ioam: add NULL check for idev in ipv6_hop_ioam()
Reported by Sashiko:
The function ipv6_hop_ioam() accesses
__in6_dev_get(skb->dev)->cnf.ioam6_enabled without validating the returned
idev pointer. Because addrconf_ifdown() can concurrently clear dev->ip6_ptr
via RCU, __in6_dev_get() can return NULL during interface teardown, which
could cause a NULL pointer dereference when processing an IOAM Hop-by-Hop
option.
Let's add a check and use SKB_DROP_REASON_IPV6DISABLED accordingly. |
| A flaw was found in dhcpcd's IPv6 Neighbor Discovery Router Advertisement processing. A specially crafted IPv6 Router Advertisement containing a zero-length Neighbor Discovery option can bypass validation during packet storage and later be reparsed without adequate validation, causing the parser to enter a non-advancing loop. Successful exploitation may result in excessive CPU consumption, leading to a denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
virt: sev-guest: Explicitly leak pages in unknown state
When set_memory_{encrypted,decrypted}() fail, the user cannot know at which
point the function failed, meaning that the pages are left in an unknown state
from the point of view of the caller.
Since the pages may be left in an unencrypted state, they are not suitable for
general use, and cannot be returned safely to the buddy allocator. Avoid the
issue by never freeing the pages, and then do the proper accounting by calling
snp_leak_pages(). |
