CVE-2022-49648 (Low severity, published 2025-02-25)
CVSS score: 4.4 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-401
Description: In the Linux kernel, the following vulnerability has been resolved:

tracing/histograms: Fix memory leak problem

This reverts commit 46bbe5c671e06f070428b9be142cc4ee5cedebac.

As commit 46bbe5c671e0 ("tracing: fix double free") said, the
"double free" problem reported by clang static analyzer is:
  > In parse_var_defs() if there is a problem allocating
  > var_defs.expr, the earlier var_defs.name is freed.
  > This free is duplicated by free_var_defs() which frees
  > the rest of the list.

However, if there is a problem allocating N-th var_defs.expr:
  + in parse_var_defs(), the freed 'earlier var_defs.name' is
    actually the N-th var_defs.name;
  + then in free_var_defs(), the names from 0th to (N-1)-th are freed;

                        IF ALLOCATING PROBLEM HAPPENED HERE!!! -+
                                                                 \
                                                                  |
          0th           1th                 (N-1)-th      N-th    V
          +-------------+-------------+-----+-------------+-----------
var_defs: | name | expr | name | expr | ... | name | expr | name | ///
          +-------------+-------------+-----+-------------+-----------

These two frees don't act on same name, so there was no "double free"
problem before. Conversely, after that commit, we get a "memory leak"
problem because the above "N-th var_defs.name" is not freed.

If enable CONFIG_DEBUG_KMEMLEAK and inject a fault at where the N-th
var_defs.expr allocated, then execute on shell like:
  $ echo 'hist:key=call_site:val=$v1,$v2:v1=bytes_req,v2=bytes_alloc' > \
/sys/kernel/debug/tracing/events/kmem/kmalloc/trigger

Then kmemleak reports:

Description: In the Linux kernel, the following vulnerability has been resolved:

stmmac: intel: Add a missing clk_disable_unprepare() call in intel_eth_pci_remove()

Commit 09f012e64e4b ("stmmac: intel: Fix clock handling on error and remove
paths") removed this clk_disable_unprepare()

This was partly revert by commit ac322f86b56c ("net: stmmac: Fix clock
handling on remove path") which removed this clk_disable_unprepare()
because:
"
   While unloading the dwmac-intel driver, clk_disable_unprepare() is
   being called twice in stmmac_dvr_remove() and
   intel_eth_pci_remove(). This causes kernel panic on the second call.
"

However later on, commit 5ec55823438e8 ("net: stmmac: add clocks management
for gmac driver") has updated stmmac_dvr_remove() which do not call
clk_disable_unprepare() anymore.

So this call should now be called from intel_eth_pci_remove().

pinctrl: devicetree: fix null pointer dereferencing in pinctrl_dt_to_map

Here is the BUG report by KASAN about null pointer dereference:

BUG: KASAN: null-ptr-deref in strcmp+0x2e/0x50
Read of size 1 at addr 0000000000000000 by task python3/2640
Call Trace:
 strcmp
 __of_find_property

 pinctrl_dt_to_map

kasprintf() would return NULL pointer when kmalloc() fail to allocate.
So directly return ENOMEM, if kasprintf() return NULL pointer.
Statement: A local denial-of-service vulnerability exists in the Linux kernel's pin control subsystem. When kasprintf() fails due to memory exhaustion, the returned NULL pointer is not checked, resulting in a NULL pointer dereference during a subsequent call to strcmp(). This issue can be triggered by a local attacker who manages to exhaust kernel memory (kmalloc failure) in a context where pinctrl_dt_to_map() is executed — such as via device-tree based driver initialization. Privileges Required is High, because requires control over kernel memory allocation environment or device-tree context (e.g., during module loading or crafted devicetree blob).

Description: In the Linux kernel, the following vulnerability has been resolved:

rxrpc: Fix locking in rxrpc's sendmsg

Fix three bugs in the rxrpc's sendmsg implementation:

 (1) rxrpc_new_client_call() should release the socket lock when returning
     an error from rxrpc_get_call_slot().

 (2) rxrpc_wait_for_tx_window_intr() will return without the call mutex
     held in the event that we're interrupted by a signal whilst waiting
     for tx space on the socket or relocking the call mutex afterwards.

     Fix this by: (a) moving the unlock/lock of the call mutex up to
     rxrpc_send_data() such that the lock is not held around all of
     rxrpc_wait_for_tx_window*() and (b) indicating to higher callers
     whether we're return with the lock dropped.  Note that this means
     recvmsg() will not block on this call whilst we're waiting.

 (3) After dropping and regaining the call mutex, rxrpc_send_data() needs
     to go and recheck the state of the tx_pending buffer and the
     tx_total_len check in case we raced with another sendmsg() on the same
     call.

Thinking on this some more, it might make sense to have different locks for
sendmsg() and recvmsg().  There's probably no need to make recvmsg() wait
for sendmsg().  It does mean that recvmsg() can return MSG_EOR indicating
that a call is dead before a sendmsg() to that call returns - but that can
currently happen anyway.

Without fix (2), something like the following can be induced:

CVE-2022-49074 (Moderate severity, published 2025-02-25)
CVSS score: 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CWE: CWE-20
Description: In the Linux kernel, the following vulnerability has been resolved:

irqchip/gic-v3: Fix GICR_CTLR.RWP polling

It turns out that our polling of RWP is totally wrong when checking
for it in the redistributors, as we test the *distributor* bit index,
whereas it is a different bit number in the RDs... Oopsie boo.

This is embarassing. Not only because it is wrong, but also because
it took *8 years* to notice the blunder...

Just fix the damn thing.
