Vulnerabilidades

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Validate NIX maximum LFs correctly NIX maximum number of LFs can be set via devlink command but that can be done before assigning any LFs to a PF/VF. The condition used to check whether any LFs are assigned is incorrect. This patch fixes…

In the Linux kernel, the following vulnerability has been resolved: net: mvneta: re-enable percpu interrupt on resume On Marvell MPIC platforms (Armada 370/XP/38x), mvneta uses a percpu IRQ disable/enable scheme for NAPI: the ISR (mvneta_percpu_isr) calls disable_percpu_irq() to mask the MPIC per-CPU interrupt and…

In the Linux kernel, the following vulnerability has been resolved: geneve: gate GRO hint in geneve_gro_complete() on gs->gro_hint geneve_gro_receive() reads the GRO hint through geneve_sk_gro_hint_off(), which honours it only when the socket enabled IFLA_GENEVE_GRO_HINT (gs->gro_hint). geneve_gro_complete() instead…

In the Linux kernel, the following vulnerability has been resolved: geneve: validate inner network offset in geneve_gro_complete() Even with both paths gated on gs->gro_hint, geneve_gro_complete() re-derives the inner dispatch type and length from the packet and the current gs->gro_hint, independently of…

In the Linux kernel, the following vulnerability has been resolved: net: sungem: fix probe error cleanup gem_init_one() calls gem_remove_one() when register_netdev() fails. gem_remove_one() unregisters and frees resources owned by the net_device, including the DMA block, MMIO mapping, PCI regions, and the net_device…

In the Linux kernel, the following vulnerability has been resolved: net: udp_tunnel: prevent double queueing in udp_tunnel_nic_device_sync Yue Sun reported a use-after-free and debugobjects warning in udp_tunnel_nic_device_sync_work() during concurrent device operations. The workqueue core clears the internal pending…

In the Linux kernel, the following vulnerability has been resolved: tipc: fix UAF in cleanup_bearer() due to premature dst_cache_destroy() TIPC UDP media bearer teardown calls dst_cache_destroy() on its replicast caches before calling synchronize_net() to wait for concurrent RCU readers (transmitters) to finish: This…

In the Linux kernel, the following vulnerability has been resolved: ALSA: FCP: Fix NULL pointer dereference in interface lookup A malformed USB device can provide a vendor-specific interface without any endpoint descriptors. fcp_find_fc_interface() currently selects the first vendor-specific interface and reads…

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix insn_aux_data leak on verifier err_free_env path When bpf_check() allocates env->insn_aux_data successfully but later fails to allocate env->succ, it jumps directly to err_free_env. The existing vfree(env->insn_aux_data) sits before the…

In the Linux kernel, the following vulnerability has been resolved: seg6: validate SRH length before reading fixed fields seg6_validate_srh() reads fixed SRH fields such as srh->type and srh->hdrlen before checking that the supplied length covers the fixed struct ipv6_sr_hdr fields. The BPF SEG6 encap path reaches…

In the Linux kernel, the following vulnerability has been resolved: net: enetc: check the number of BDs needed for xdp_frame The size of xdp_redirect_arr array is ENETC_MAX_SKB_FRAGS. However, the number of fragments contained in xdp_frame may be greater than or equal to ENETC_MAX_SKB_FRAGS, which will cause the…

In the Linux kernel, the following vulnerability has been resolved: sctp: add INIT verification after cookie unpacking In SCTP handshake, the INIT chunk is initially processed by the server and embedded into the cookie carried in INIT-ACK. The client then returns this cookie via COOKIE-ECHO, where the server unpacks…

In the Linux kernel, the following vulnerability has been resolved: hwmon: (pmbus/core) honor vrm_version in pmbus_data2reg_vid() pmbus_data2reg_vid() hardcoded the VR11 encoding regardless of the vrm_version configured by the driver, while pmbus_reg2data_vid() already switched on it. Any driver that selects a…

In the Linux kernel, the following vulnerability has been resolved: hwmon: adm1275: Prevent reading uninitialized stack While adding support for the ROHM BD127X0 hot-swap controllers, sashiko reported an error in device-name comparison, which can lead to reading uninitialized stack memory. Quoting Sashiko: This is a…

In the Linux kernel, the following vulnerability has been resolved: hwmon: (pmbus) Fix passing events to regulator core Sashiko reports: Commit 754bd2b4a084 ("hwmon: (pmbus/core) Protect regulator operations with mutex") introduced a worker to batch regulator events over time using atomic_or(). The delayed worker then…

In the Linux kernel, the following vulnerability has been resolved: hwmon: (aspeed-g6-pwm-tach) Guard fan RPM calculation against divide-by-zero Sashiko reports: In the aspeed-g6-pwm-tacho driver, the aspeed_tach_val_to_rpm() function calculates the fan RPM using the tachometer value. However, it does not check if the…

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: don't cache shinfo across skb realloc fbnic_tx_lso() calls skb_cow_head() which may reallocate the skb including the shared info. We can't use the pointer calculated before the call.

In the Linux kernel, the following vulnerability has been resolved: ipv6: fib6: fix NULL deref in fib6_walk_continue() on multi-batch dump inet6_dump_fib() saves its progress in cb->args[1] as a positional index within the current hash chain. Between batches, a concurrent fib6_new_table() can insert a new table at the…

In the Linux kernel, the following vulnerability has been resolved: net: phy: sfp: free mii_bus in sfp_i2c_mdiobus_destroy sfp_i2c_mdiobus_create() allocates the I2C MDIO bus with mdio_i2c_alloc(), a plain (non-devm) allocation, and registers it. sfp_i2c_mdiobus_destroy() only unregisters the bus and clears…

In the Linux kernel, the following vulnerability has been resolved: net/sched: sch_teql: Introduce slaves_lock to avoid race condition and UAF The teql master->slaves singly linked list is not protected against multiple writes. It can be mod'ed concurently from teql_master_xmit(), teql_dequeue(), teql_init() and…

In the Linux kernel, the following vulnerability has been resolved: bridge: stp: Fix a potential use-after-free when deleting a bridge The three STP timers are not supposed to be armed while the bridge is administratively down. They are synchronously deactivated when the bridge is put administratively down and the…

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Always use the IRQ-safe variant when acquiring the fence lock Since dma_fence objects can be shared with other subsystems, they may be accessed from hardirq context in those drivers, and we have to take that into account by also using the…

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Fix potential invalid pointer deref in group_process_tiler_oom() If heaps is an ERR_PTR(), panthor_heap_pool_put() will deref an invalid pointer. Make sure we set it to NULL in that case.

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Fix a leak when a group is evicted before the tiler OOM is serviced A group ref is tied to the pending tiler_oom_work, so we need to release it if the cancel was effective.

In the Linux kernel, the following vulnerability has been resolved: tracing/fprobe: Fix NULL pointer dereference in fprobe_fgraph_entry() fprobe_fgraph_entry() sizes a shadow-stack reservation in one walk of the per-ip fprobe list and fills it in a second walk, both under rcu_read_lock() only. A fprobe registered on…
