irqchip/gic-v5: Immediately exec priority drop following activate

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v5: Immediately exec priority drop following activate With GICv5 an interrupt of equal or lower priority cannot be signalled until there has been a priority drop. This is done via the GIC CDEOI system instruction. Once this has been executed, the hardware is able to signal the next interrupt if there is one. As all interrupts are programmed to have the same priority, no new interrupts can be signalled until the priority drop has happened. This can cause issues when, for example, an interrupt remains active while a long running process takes place, such as when

irqchip/gic-v4: Don't advertise VLPIs if no ITS is probed

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v4: Don't advertise VLPIs if no ITS is probed When accidentally setting “kvm-arm.vgic_v4_enable=1” on a system that has no MSI controller device tree node and GICv4, it results a panic as “gic_domain” is NULL and the kernel attempts to access it.

host1x: bus: Fix missing ops null check in error teardown

In the Linux kernel, the following vulnerability has been resolved: host1x: bus: Fix missing ops null check in error teardown In host1x_device_init(), the error teardown paths do not check client->ops before dereferencing it, unlike the forward init paths which correctly guard with 'client->ops &&'. This can result in a NULL pointer dereference if client->ops is NULL. Fix by adding the missing client->ops check in both the teardown and teardown_late labels.

drm/nouveau/gsp: add SEC2 to GA100 chip table

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/gsp: add SEC2 to GA100 chip table The booter-load and booter-unload firmware run on the SEC2 falcon. During tu102_gsp_oneinit(), the booter constructor needs device->sec2 to access the SEC2 falcon. Without the .sec2 entry, device->sec2 is NULL and this dereference crashes during GSP-RM boot.

wifi: iwlwifi: mld: don't WARN on WoWLAN suspend w/o netdetect

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: don't WARN on WoWLAN suspend w/o netdetect Clearly, from a user perspective, it must be valid to configure WoWLAN and then suspend while not connected to a network. Since mac80211 doesn't distinguish these cases and simply calls the driver to suspend whenever WoWLAN is configured, the driver has to cleanly handle the case where it's called for WoWLAN, it's not connected but there's also no netdetect configured. Remove the WARN_ON() and keep returning 1 to disconnect and then suspend.

netfilter: nf_conntrack_expect: zero at allocation time

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_conntrack_expect: zero at allocation time There are occasional LLM hints wrt. leaking uninitialized data to userspace via ctnetlink. Just zero at allocation time, expectations are not frequently used these days. Intentionally keeps _init as-is because we could theoretically support re-init, so add the missing exp->dir there.

freevxfs: don't BUG() on unknown typed-extent type

In the Linux kernel, the following vulnerability has been resolved: freevxfs: don't BUG() on unknown typed-extent type vxfs_bmap_typed() handles four typed-extent types and calls BUG() in its default case, so an on-disk typed extent with any other type value crashes the kernel. It is reachable from ioctl(FIBMAP) on a regular file: kernel BUG at fs/freevxfs/vxfs_bmap.c:230! RIP: vxfs_bmap_typed fs/freevxfs/vxfs_bmap.c:230 [inline] vxfs_bmap1+0x128a/0x12d0 fs/freevxfs/vxfs_bmap.c:257 Replace the BUG() with WARN_ON_ONCE() and return 0 -- the value vxfs_bmap_typed() already returns on failure (and from the DEV4 case above); vxfs_ge

crypto: ccp - Fix possible deadlock in SEV init failure path

In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Fix possible deadlock in SEV init failure path __sev_platform_init_handle_init_ex_path() calls rmp_mark_pages_firmware() with locked=false while the parent function of init_ex_path already acquired the sev_cmd_mutex. In the case of an RMPUPDATE failure for any page after the first, the cleanup path would invoke reclaim pages which would result in a deadlock in sev_do_cmd. Pass locked=true to honor the lock status of the parent function.

ksmbd: remove stale channels from all sessions on teardown

In the Linux kernel, the following vulnerability has been resolved: ksmbd: remove stale channels from all sessions on teardown ksmbd_sessions_deregister() removes a connection's channels from other sessions' channel lists only while conn->binding is still set: if (conn->binding) { hash_for_each_safe(sessions_table, ...) ksmbd_chann_del(conn, sess); } conn->binding is a transient flag: it is cleared once a binding SESSION_SETUP completes, and also by a subsequent non-binding SESSION_SETUP on the same connection (a reauthentication on a bound channel, or a new SessionId==0 setup). A connection that has bound a channel into another se

Snap7 through 1.4.3 Out-of-Bounds Write via BRecv and CheckAsBRecvCompletion

Snap7 through 1.4.3 contains an out-of-bounds write vulnerability in the passive partner that allows a malicious active partner to overflow application buffers by declaring an unvalidated BSend total length. Attackers connecting from the configured peer address can declare up to 65535 bytes and send a short fragment, causing BRecv to memcpy past the buffer and crash or corrupt SCADA, HMI or gateway processes.

RPly through 1.1.4 Out-of-Bounds Function Pointer Index via PLY Header

RPly through 1.1.4 contains an improper array index validation vulnerability in ply_read_header_property() that accepts list as a list property's length or value type. Attackers can supply a crafted PLY file that makes ply_read_list_property() call an out-of-bounds handler, crashing ASCII parsing or corrupting memory in binary parsing.
