wifi: iwlwifi: mld: purge async notifications upon nic error
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mld: purge async notifications upon nic error
This fixes a kernel panic in reconfig failure:
1. we have a BSS connection
2. we have a NAN connection
3. FW error occurs
4. reconfig restores the BSS connection
5. however, restoring the NAN connection fails due to a FW error.
6. erroneously, ieee80211_handle_reconfig_failure is called and marks all
interfaces as not-in-driver (will be fixed in a different patch).
7. mac80211 frees the links of the BSS connection but doesn't tell the
driver about that, as it thinks that this vif is not in the driver.
8. in

powercap: intel_rapl: Fix memory leak in rapl_add_package_cpuslocked()
In the Linux kernel, the following vulnerability has been resolved:
powercap: intel_rapl: Fix memory leak in rapl_add_package_cpuslocked()
When topology_physical_package_id()/topology_logical_die_id() returns
a negative value, rapl_add_package_cpuslocked() returns ERR_PTR(-EINVAL)
directly without freeing the rapl_package structure that was just
allocated by kzalloc_obj(), leaking memory on every failed package
addition.
Use the existing err_free_package label so that the allocation is
released on the error path.

ipv6: addrconf: fix temp address generation after prefix deprecation
In the Linux kernel, the following vulnerability has been resolved:
ipv6: addrconf: fix temp address generation after prefix deprecation
When a router temporarily deprecates an IPv6 prefix (either by sending a
Router Advertisement with Preferred Lifetime = 0 or by letting the
lifetime expire) and later restores it, the kernel permanently loses its
ability to generate temporary privacy addresses (RFC 8981) for that
prefix.
This happens because the address worker attempts to generate a
replacement temporary address when the current one nears expiration. As
the base prefix is deprecated already, the generation fails after
marking the temporar

ACPICA: Fix NULL pointer dereference in acpi_ns_custom_package()
In the Linux kernel, the following vulnerability has been resolved:
ACPICA: Fix NULL pointer dereference in acpi_ns_custom_package()
acpi_ns_custom_package() unconditionally dereferences the first element
of the package to read the _BIX version number, without checking for
NULL:
if ((*Elements)->Common.Type != ACPI_TYPE_INTEGER)
When firmware returns a _BIX package whose first element is an
unresolvable reference, ACPICA evaluates that entry to NULL.
acpi_ns_remove_null_elements() does not strip NULL entries for
ACPI_PTYPE_CUSTOM packages (fixed-position format would break if
elements were shifted), so acpi_ns_custom_package() sees th

perf/ftrace: Fix WARNING in __unregister_ftrace_function
In the Linux kernel, the following vulnerability has been resolved:
perf/ftrace: Fix WARNING in __unregister_ftrace_function
perf_ftrace_function_unregister() unconditionally calls
unregister_ftrace_function() without checking whether the ftrace_ops
was ever successfully registered. This triggers a WARN_ON in
__unregister_ftrace_function() when the ops doesn't have
FTRACE_OPS_FL_ENABLED set.
This can happen during perf_event_alloc() error cleanup when
perf_trace_destroy() is called via __free_event() on an event whose
ftrace_ops registration failed or was already torn down by
perf_try_init_event()'s err_destroy path.

wifi: ath11k: fix invalid data access in ath11k_dp_rx_h_undecap_nwifi
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix invalid data access in ath11k_dp_rx_h_undecap_nwifi
In certain cases, hardware might provide packets with a
length greater than the maximum native Wi-Fi header length.
This can lead to accessing and modifying fields in the header
within the ath11k_dp_rx_h_undecap_nwifi() function for the
DP_RX_DECAP_TYPE_NATIVE_WIFI decap type and
potentially result in invalid data access and memory corruption.

ata: ahci: fail probe if BAR too small for claimed ports
In the Linux kernel, the following vulnerability has been resolved:
ata: ahci: fail probe if BAR too small for claimed ports
When an AHCI controller is disabled in BIOS, its HOST_CAP register may
contain a bogus value, e.g. 0xFFFFFFFF.
Since CAP.NP (Number of Ports) is a zeroes based 5-bit register field,
a value of 0x1f means 32 ports. If CAP.NP claims more ports than can
physically fit within the mapped BAR region, accessing port registers
beyond the BAR boundary causes a kernel panic.
Add validation in ahci_init_one() to check that the BAR size is
sufficient for the number of ports claimed in CAP.NP. The check
calculates the required M

net: qrtr: fix node refcount leak on ctrl packet alloc failure
qrtr_send_resume_tx() calls qrtr_node_lookup() which takes a
reference on the returned node. If the subsequent call to
qrtr_alloc_ctrl_packet() fails due to memory allocation failure, the
function returns -ENOMEM without calling qrtr_node_release() to
release the node reference.
Add qrtr_node_release(node) before returning on the allocation failure
path to properly release the reference.
