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

rds: filter RDS_INFO_* getsockopt by caller's netns

In the Linux kernel, the following vulnerability has been resolved: rds: filter RDS_INFO_* getsockopt by caller's netns The RDS_INFO_* family of getsockopt(2) options reads several file-scope global lists that are not per-netns: rds_sock_info / rds6_sock_info, rds_sock_inc_info / rds6_sock_inc_info -> rds_sock_list rds_tcp_tc_info / rds6_tcp_tc_info -> rds_tcp_tc_list rds_conn_info / rds6_conn_info, rds_conn_message_info_cmn (for the *_SEND_MESSAGES and *_RETRANS_MESSAGES variants), rds_for_each_conn_info (for RDS_INFO_IB_CONNECTIONS) -> rds_conn_hash[] The ha

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

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. The call path is: p

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
