    tty: serial: 8250: protect against NULL uart->port.dev in register

    In the Linux kernel, the following vulnerability has been resolved: tty: serial: 8250: protect against NULL uart->port.dev in register serial8250_register_8250_port() conditionally copies uart->port.dev from up->port.dev only when up->port.dev is non-NULL: if (up->port.dev) { uart->port.dev = up->port.dev; ... } So if both the existing uart slot and up have a NULL ->dev, uart->port.dev remains NULL. The very next ACPI companion check then dereferences it unconditionally: if (!has_acpi_companion(uart->port.dev)) { has_acpi_companion() reads dev->fwnode without a NULL guard (include/linux/acpi.h), so this NULL-derefs the kernel for

    RDMA/counter: Fix num_counters leak on bind_qp failure in alloc_and_bind()

    In the Linux kernel, the following vulnerability has been resolved: RDMA/counter: Fix num_counters leak on bind_qp failure in alloc_and_bind() When __rdma_counter_bind_qp() fails in alloc_and_bind(), the error path jumps to err_mode which frees the counter without decrementing port_counter->num_counters. The only place that decrements is rdma_counter_free(), which is unreachable since the counter was never successfully bound. This leak accumulates across repeated failures, permanently preventing the port from switching to AUTO mode (-EBUSY in __counter_set_mode()) and blocking the MANUAL→NONE auto-revert in rdma_counter_free(). When the mo

    thermal/drivers/tegra/soctherma: Switch to devm cooling device registration

    In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/tegra/soctherma: Switch to devm cooling device registration Use devm_thermal_of_cooling_device_register() to simplify resource management and avoid manual cleanup in error paths. As a side effect this change has the benefit of solving an existing issue. Before, the function tegra_soctherm_remove() only called debugfs_remove_recursive() and never called thermal_cooling_device_unregister() for any of the cooling devices registered here. After the driver removal, the thermal framework's cdev list would still hold references to thermal_cooling_device objects w

    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
