| In the Linux kernel, the following vulnerability has been resolved:
power: supply: bq25980: Fix use-after-free in power_supply_changed()
Using the `devm_` variant for requesting IRQ _before_ the `devm_`
variant for allocating/registering the `power_supply` handle, means that
the `power_supply` handle will be deallocated/unregistered _before_ the
interrupt handler (since `devm_` naturally deallocates in reverse
allocation order). This means that during removal, there is a race
condition where an interrupt can fire just _after_ the `power_supply`
handle has been freed, *but* just _before_ the corresponding
unregistration of the IRQ handler has run.
This will lead to the IRQ handler calling `power_supply_changed()` with
a freed `power_supply` handle. Which usually crashes the system or
otherwise silently corrupts the memory...
Note that there is a similar situation which can also happen during
`probe()`; the possibility of an interrupt firing _before_ registering
the `power_supply` handle. This would then lead to the nasty situation
of using the `power_supply` handle *uninitialized* in
`power_supply_changed()`.
Fix this racy use-after-free by making sure the IRQ is requested _after_
the registration of the `power_supply` handle. |

| In the Linux kernel, the following vulnerability has been resolved:
crypto: caam - fix netdev memory leak in dpaa2_caam_probe
When commit 0e1a4d427f58 ("crypto: caam: Unembed net_dev structure in
dpaa2") converted embedded net_device to dynamically allocated pointers,
it added cleanup in dpaa2_dpseci_disable() but missed adding cleanup in
dpaa2_dpseci_free() for error paths.
This causes memory leaks when dpaa2_dpseci_dpio_setup() fails during probe
due to DPIO devices not being ready yet. The kernel's deferred probe
mechanism handles the retry successfully, but the netdevs allocated during
the failed probe attempt are never freed, resulting in kmemleak reports
showing multiple leaked netdev-related allocations all traced back to
dpaa2_caam_probe().
Fix this by preserving the CPU mask of allocated netdevs during setup and
using it for cleanup in dpaa2_dpseci_free(). This approach ensures that
only the CPUs that actually had netdevs allocated will be cleaned up,
avoiding potential issues with CPU hotplug scenarios. |

| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Fix memory leak in amdxdna_ubuf_map
The amdxdna_ubuf_map() function allocates memory for sg and
internal sg table structures, but it fails to free them if subsequent
operations (sg_alloc_table_from_pages or dma_map_sgtable) fail. |
| In the Linux kernel, the following vulnerability has been resolved:
tpm2-sessions: Fix missing tpm_buf_destroy() in tpm2_read_public()
tpm2_read_public() calls tpm_buf_init() but fails to call
tpm_buf_destroy() on two exit paths, leaking a page allocation:
1. When name_size() returns an error (unrecognized hash algorithm),
the function returns directly without destroying the buffer.
2. On the success path, the buffer is never destroyed before
returning.
All other error paths in the function correctly call
tpm_buf_destroy() before returning.
Fix both by adding the missing tpm_buf_destroy() calls. |

Input: edt-ft5x06 - fix use-after-free in debugfs teardown
The commit 68743c500c6e ("Input: edt-ft5x06 - use per-client debugfs
directory") removed the manual debugfs teardown, relying on the I2C core
to handle it. However, this creates a window where debugfs files are
still accessible after edt_ft5x06_ts_teardown_debugfs() frees
tsdata->raw_buffer.
To prevent a use-after-free, protect the freeing of raw_buffer with the
device mutex and set raw_buffer to NULL. The debugfs read function
already checks if raw_buffer is NULL under the same mutex, so this
safely avoids the use-after-free. |

| In the Linux kernel, the following vulnerability has been resolved:
pinctrl: single: fix refcount leak in pcs_add_gpio_func()
of_parse_phandle_with_args() returns a device_node pointer with refcount
incremented in gpiospec.np. The loop iterates through all phandles but
never releases the reference, causing a refcount leak on each iteration.
Add of_node_put() calls to release the reference after extracting the
needed arguments and on the error path when devm_kzalloc() fails.
This bug was detected by our static analysis tool and verified by my
code review. |
| In the Linux kernel, the following vulnerability has been resolved:
phy: freescale: imx8qm-hsio: fix NULL pointer dereference
During the probe the refclk_pad pointer is set to NULL if the
'fsl,refclk-pad-mode' property is not defined in the devicetree node. But
in imx_hsio_configure_clk_pad() this pointer is unconditionally used which
could result in a NULL pointer dereference. So check the pointer before to
use it. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix NULL sock in aa_sock_file_perm
Deal with the potential that sock and sock-sk can be NULL during
socket setup or teardown. This could lead to an oops. The fix for NULL
pointer dereference in __unix_needs_revalidation shows this is at
least possible for af_unix sockets. While the fix for af_unix sockets
applies for newer mediation this is still the fall back path for older
af_unix mediation and other sockets, so ensure it is covered. |

fs/ntfs3: fix deadlock in ni_read_folio_cmpr
Syzbot reported a task hung in ni_readpage_cmpr (now ni_read_folio_cmpr).
This is caused by a lock inversion deadlock involving the inode mutex
(ni_lock) and page locks.
Scenario:
1. Task A enters ntfs_read_folio() for page X. It acquires ni_lock.
2. Task A calls ni_read_folio_cmpr(), which attempts to lock all pages in
the compressed frame (including page Y).
3. Concurrently, Task B (e.g., via readahead) has locked page Y and
calls ntfs_read_folio().
4. Task B waits for ni_lock (held by A).
5. Task A waits for page Y lock (held by B).
-> DEADLOCK.
The fix is to restructure locking: do not take ni_lock in ntfs_read_folio().
Instead, acquire ni_lock inside ni_read_folio_cmpr() ONLY AFTER all required
page locks for the frame have been successfully acquired. This restores the
correct lock ordering (Page Lock -> ni_lock) consistent with VFS.
[almaz.alexandrovich@paragon-software.com: ni_readpage_cmpr was renamed to ni_read_folio_cmpr] |

staging: rtl8723bs: properly validate the data in rtw_get_ie_ex()
Just like in commit 154828bf9559 ("staging: rtl8723bs: fix out-of-bounds
read in rtw_get_ie() parser"), we don't trust the data in the frame so
we should check the length better before acting on it |
