| In the Linux kernel, the following vulnerability has been resolved:
drm/edid: fix info leak when failing to get panel id
Make sure to clear the transfer buffer before fetching the EDID to
avoid leaking slab data to the logs on errors that leave the buffer
unchanged. |
| In the Linux kernel, the following vulnerability has been resolved:
vp_vdpa: fix the crash in hot unplug with vp_vdpa
While unplugging the vp_vdpa device, it triggers a kernel panic
The root cause is: vdpa_mgmtdev_unregister() will accesses modern
devices which will cause a use after free.
So need to change the sequence in vp_vdpa_remove

| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix steering rules cleanup
vport's mc, uc and multicast rules are not deleted in teardown path when
EEH happens. Since the vport's promisc settings(uc, mc and all) in
firmware are reset after EEH, mlx5 driver will try to delete the above
rules in the initialization path. This cause kernel crash because these
software rules are no longer valid.
Fix by nullifying these rules right after delete to avoid accessing any dangling
pointers.

drm/amd/display: fix shift-out-of-bounds in CalculateVMAndRowBytes
[WHY]
When PTEBufferSizeInRequests is zero, UBSAN reports the following
warning because dml_log2 returns an unexpected negative value:
shift exponent 4294966273 is too large for 32-bit type 'int'
[HOW]
In the case PTEBufferSizeInRequests is zero, skip the dml_log2() and
assign the result directly. |

When checking pg->records[pg->index - 1].ip in lookup_rec(), it can get a
pg which is newly added to ftrace_pages_start in ftrace_process_locs().
Before the first pg->index++, index is 0 and accessing pg->records[-1].ip
will cause this problem.
Don't check the ip when pg->index is 0. |

drm/amdgpu: fix ttm_bo calltrace warning in psp_hw_fini
The call trace occurs when the amdgpu is removed after
the mode1 reset. During mode1 reset, from suspend to resume,
there is no need to reinitialize the ta firmware buffer
which caused the bo pin_count increase redundantly.

| In the Linux kernel, the following vulnerability has been resolved:
perf/x86/amd/core: Always clear status for idx
The variable 'status' (which contains the unhandled overflow bits) is
not being properly masked in some cases, displaying the following
warning:
WARNING: CPU: 156 PID: 475601 at arch/x86/events/amd/core.c:972 amd_pmu_v2_handle_irq+0x216/0x270
This seems to be happening because the loop is being continued before
the status bit being unset, in case x86_perf_event_set_period()
returns 0. This is also causing an inconsistency because the "handled"
counter is incremented, but the status bit is not cleaned.
Move the bit cleaning together above, together when the "handled"
counter is incremented. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: do not run mt76_unregister_device() on unregistered hw
Trying to probe a mt7921e pci card without firmware results in a
successful probe where ieee80211_register_hw hasn't been called. When
removing the driver, ieee802111_unregister_hw is called unconditionally
leading to a kernel NULL pointer dereference.
Fix the issue running mt76_unregister_device routine just for registered
hw. |

ACPI: PPTT: Fix to avoid sleep in the atomic context when PPTT is absent
Commit 0c80f9e165f8 ("ACPI: PPTT: Leave the table mapped for the runtime usage")
enabled to map PPTT once on the first invocation of acpi_get_pptt() and
never unmapped the same allowing it to be used at runtime with out the
hassle of mapping and unmapping the table. This was needed to fetch LLC
information from the PPTT in the cpuhotplug path which is executed in
the atomic context as the acpi_get_table() might sleep waiting for a
mutex.
However it missed to handle the case when there is no PPTT on the system
which results in acpi_get_pptt() being called from all the secondary
CPUs attempting to fetch the LLC information in the atomic context
without knowing the absence of PPTT resulting in the splat like below:

is not available on the system and return NULL avoiding any attempts to
fetch PPTT and thereby avoiding any possible sleep waiting for a mutex
in the atomic context. |

avoid any races. This patch removes the useless rtnl_(un)lock to guarantee
correctness. |

| In the Linux kernel, the following vulnerability has been resolved:
fscrypt: destroy keyring after security_sb_delete()
fscrypt_destroy_keyring() must be called after all potentially-encrypted
inodes were evicted; otherwise it cannot safely destroy the keyring.
Since inodes that are in-use by the Landlock LSM don't get evicted until
security_sb_delete(), this means that fscrypt_destroy_keyring() must be
called *after* security_sb_delete().
This fixes a WARN_ON followed by a NULL dereference, only possible if
Landlock was being used on encrypted files. |
| In the Linux kernel, the following vulnerability has been resolved:
erspan: do not use skb_mac_header() in ndo_start_xmit()
Drivers should not assume skb_mac_header(skb) == skb->data in their
ndo_start_xmit().
Use skb_network_offset() and skb_transport_offset() which
better describe what is needed in erspan_fb_xmit() and
ip6erspan_tunnel_xmit()

| In the Linux kernel, the following vulnerability has been resolved:
dm crypt: add cond_resched() to dmcrypt_write()
The loop in dmcrypt_write may be running for unbounded amount of time,
thus we need cond_resched() in it.
This commit fixes the following warning:

| In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Fix memory leak in margining
Memory for the usb4->margining needs to be relased for the upstream port
of the router as well, even though the debugfs directory gets released
with the router device removal. Fix this. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: ucsi: Fix NULL pointer deref in ucsi_connector_change()
When ucsi_init() fails, ucsi->connector is NULL, yet in case of
ucsi_acpi we may still get events which cause the ucs_acpi code to call
ucsi_connector_change(), which then derefs the NULL ucsi->connector
pointer.
Fix this by not setting ucsi->ntfy inside ucsi_init() until ucsi_init()
has succeeded, so that ucsi_connector_change() ignores the events
because UCSI_ENABLE_NTFY_CONNECTOR_CHANGE is not set in the ntfy mask. |
