In the Linux kernel, the following vulnerability has been resolved: net: ti: icssm-prueth: fix eth_ports_node leak in probe The error path on of_property_read_u32() failure inside icssm_prueth_probe() returns without putting eth_ports_node, which was acquired before the for_each_child_of_node() loop. Drop it before returning.

In the Linux kernel, the following vulnerability has been resolved: btrfs: tracepoints: fix sleep while in atomic context in btrfs_sync_file() The trace event btrfs_sync_file() is called in an atomic context (all trace events are) and its call to dput(), which is needed due to the call to dget_parent(), can sleep, triggering a kernel splat. This can be reproduced by enabling the trace event and running btrfs/056 from fstests for example. The splat shown in dmesg is the following: [53.919]

In the Linux kernel, the following vulnerability has been resolved: test_kprobes: clear kprobes between test runs Running the kprobes sanity tests twice makes all tests fail and eventually crashes the kernel. [root@martin-riscv-1 ~]# echo 1 > /sys/kernel/debug/kunit/kprobes_test/run ... # Totals: pass:5 fail:0 skip:0 total:5 ok 1 kprobes_test [root@martin-riscv-1 ~]# echo 1 > /sys/kernel/debug/kunit/kprobes_test/run ... # test_kprobe: EXPECTATION FAILED at lib/tests/test_kprobes.c:64

In the Linux kernel, the following vulnerability has been resolved: phonet/pep: disable BH around forwarded sk_receive_skb() The networking receive path is usually run from softirq context, but protocols that take the socket lock may have packets stored in the backlog and processed later from process context. In that case release_sock() -> __release_sock() drops the slock with spin_unlock_bh() and then calls sk->sk_backlog_rcv() with bottom halves enabled. Typical sk_backlog_rcv handlers proc

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix driver-set TX rates on old devices On old devices such as 7265D, rates are still encoded in version 1 format, which doesn't use the CCK/OFDM rate index (0-3/0-7) but rather their PLCP value (e.g. 10 for 1 Mbps CCK rate.) While introducing v3 rates, I changed the driver from internally handling v1 rates and converting to v2, to internally handling v3 and converting to v1 or v2 according to the firmware.

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: stop TX during firmware restart When iwlwifi firmware crashes (e.g., NMI_INTERRUPT_UNKNOWN on Intel BE201/Wi-Fi 7), iwl_mld_nic_error() sets mld->fw_status.in_hw_restart to true. However, iwl_mld_tx_from_txq() does not check this flag before dequeuing frames from mac80211 and pushing them to the transport layer. Since the firmware is dead, iwl_trans_tx() returns -EIO for each frame, which then gets freed i

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: advance loop vars in cfg80211_merge_profile() cfg80211_merge_profile() reassembles a Multi-BSSID non-transmitted BSS profile that has been split across multiple consecutive MBSSID elements. Its while-loop calls cfg80211_get_profile_continuation(ie, ielen, mbssid_elem, sub_elem) but never advances mbssid_elem or sub_elem inside the body. Each iteration therefore searches for a continuation that follows the s

In the Linux kernel, the following vulnerability has been resolved: tracing: Do not call map->ops->elt_free() if elt_alloc() fails In paths where tracing_map_elt_alloc() failed to allocate objects, the map->ops->elt_alloc() call was never successful. In this case, map->ops->elt_free() should not be called.

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Disable AVIC IPI virtualization on Hygon Family 18h (erratum #1235) Hygon Family 18h CPUs are derived from AMD Family 17h (Zen1) silicon and share the same erratum #1235: hardware may read a stale IsRunning=1 bit during ICR write emulation and silently fail to generate an AVIC_IPI_FAILURE_TARGET_NOT_RUNNING VM-Exit on the sending vCPU. The absence of the VM-Exit causes KVM to miss the required wakeup of blocking tar

In the Linux kernel, the following vulnerability has been resolved: i2c: tegra: fix pm_runtime leak on mutex_lock failure If tegra_i2c_mutex_lock() fails, the function returns without calling pm_runtime_put(), leaking the runtime PM reference acquired by the preceding pm_runtime_get_sync(). This prevents the device from ever entering runtime suspend. Add the missing pm_runtime_put() before returning on lock failure.

In the Linux kernel, the following vulnerability has been resolved: spi: qup: fix error pointer deref after DMA setup failure The driver falls back to PIO mode if DMA setup fails during probe. Make sure to the clear the DMA channel pointers on setup failure to avoid dereferencing an error pointer (or attempting to release a channel a second time) on later probe errors or driver unbind. This issue was flagged by Sashiko when reviewing a devres allocation conversion patch.

In the Linux kernel, the following vulnerability has been resolved: spi: ep93xx: fix error pointer deref after DMA setup failure The driver falls back to PIO mode if DMA setup fails during probe. Make sure to the clear the DMA channel pointers on setup failure to avoid dereferencing an error pointer on later probe errors or driver unbind. This issue was flagged by Sashiko when reviewing a devres allocation conversion patch.

In the Linux kernel, the following vulnerability has been resolved: spi: sprd: fix error pointer deref after DMA setup failure The driver falls back to PIO mode if DMA setup fails during probe. Make sure to check the dma.enabled flag before trying to release the DMA channels also on late probe errors to avoid dereferencing an error pointer (or attempting to release a channel a second time). This issue was flagged by Sashiko when reviewing a devres allocation conversion patch.

In the Linux kernel, the following vulnerability has been resolved: kho: skip KHO for crash kernel kho_fill_kimage() unconditionally populates the kimage with KHO metadata for every kexec image type. When the image is a crash kernel, this can be problematic as the crash kernel can run in a small reserved region and the KHO scratch areas can sit outside it. The crash kernel then faults during kho_memory_init() when it tries phys_to_virt() on the KHO FDT address: Unable to handle kernel pagin

In the Linux kernel, the following vulnerability has been resolved: firmware: arm_ffa: Check for NULL FF-A ID table while driver registration The bus match callback assumes that every FF-A driver provides an id_table and dereferences it unconditionally. Enforce that contract at registration time so a buggy client driver cannot crash the bus during match.

In the Linux kernel, the following vulnerability has been resolved: ARM: integrator: Fix early initialization Starting with commit bdb249fce9ad4 ("ARM: integrator: read counter using syscon/regmap"), intcp_init_early calls syscon_regmap_lookup_by_compatible which in turn calls of_syscon_register. This function allocates memory. Since the memory management code has not been initialized at that time, the call always fails. It either returns -ENOMEM or crashes as follows. Unable to handle kernel

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Ensure vendor's exit handler runs before fastpath userspace exits Move the handling of fastpath userspace exits into vendor code to ensure KVM runs vendor specific operations that need to run before userspace gains control of the vCPU. E.g. for VMX (and soon to be for SVM as well), KVM needs to flush the PML buffer prior to exiting to userspace, otherwise any memory written by the final KVM_RUN might never be flagge

SurrealDB versions before 1.1.0 fail to properly parse the ID, DB, and NS headers in HTTP REST API requests containing special characters. Unauthenticated attackers can send crafted HTTP requests with malformed header values to trigger an uncaught exception that crashes the server.
