CVE-2026-80965

CVE-2026-80965 affects the ALSA serial-u16550 driver in the Linux kernel. The driver blindly trusts the devptr->id value at probe time. While this is safe for devices the driver creates itself, a device bound manually via the sysfs interface may carry a value of -1 ("none"), leading to an out-...

CVE-2026-80963

CVE-2026-80963 affects the Linux kernel 's dm-stats module (device-mapper statistics). The root cause is a NULL pointer dereference in the dm_stat_free function: when the per-CPU allocation via dm_kvzalloc fails, execution jumps to an error path that calls dm_stat_free, which iterates over all po...

CVE-2026-80964

CVE-2026-80964 affects the virmidi driver in the Linux kernel's ALSA subsystem. The driver blindly trusts the devptr->id value as a valid card index during probe. While this is safe for devices created by the driver itself at module load time, if a device is bound manually via the sysfs interf...

CVE-2026-80962

A vulnerability in the Linux kernel dm-pcache (device-mapper persistent cache) component allows a local attacker with CAP_SYS_ADMIN to trigger an out-of-bounds read and write by supplying a cache device with invalid on-disk geometry metadata. The root cause is that cache_segs_init() and get_seg_i...

CVE-2026-80961

CVE-2026-80961 affects the dm-pcache (Device-Mapper Persistent Cache) component of the Linux kernel . Two fields decoded from the cache device are left unbounded: the kset key_num , which can exceed the PCACHE_KSET_KEYS_MAX buffer before the CRC comparison, and the key's intra-segment offset and ...

CVE-2026-80960

CVE-2026-80960 is an out-of-bounds write vulnerability in the Linux kernel's dm-pcache (device-mapper persistent cache) module. The on-media seg_num field, read from a crc32c-only superblock, is attacker-controlled by anyone with CAP_SYS_ADMIN who supplies the cache device at table load. It is ne...

CVE-2026-80959

CVE-2026-80959 affects the Linux kernel's dm-pcache (device-mapper persistent cache) component. The root cause is in cache_pos_decode() , which uses persisted key_tail and dirty_tail seg_off values to address data within a cache segment. A seg_off at or past the segment data_size , controllable b...

CVE-2026-80957

CVE-2026-80957 affects the dm-pcache subsystem in the Linux kernel . The function cache_replay() traverses the on-media last-kset chain via next_cache_seg_id without calling cond_resched(). A forged chain that points back into an already-visited segment causes the replay loop to iterate indefinit...

CVE-2026-80958

CVE-2026-80958 is a buffer over-read in the Linux kernel's dm-pcache (Device Mapper Persistent Cache) component. The tail-kset read performed by cache_replay(), the writeback worker, and the garbage collection (GC) worker incorrectly bounds its length by PCACHE_SEG_SIZE - seg_off (the raw segment...

CVE-2026-80956

CVE-2026-80956 affects the Linux kernel's dm-pcache (device mapper persistent cache) subsystem. The root cause is a bounds mismatch: get_cache_segment() scans the segment map up to cache->n_segs (the physical device segment count), while cache_segs_init() only initializes the first cache_info-...

CVE-2026-80955

CVE-2026-80955 is a use-after-free vulnerability in the Linux kernel's dm-pcache module, within the kset_replay() function. When a key's segment generation (key->seg_gen) is stale, cache_key_put(key) frees the key memory, but key->cache_pos.cache_seg is subsequently accessed as an argument ...

CVE-2026-80954

CVE-2026-80954 affects the Linux kernel's i3c subsystem . The function i3c_device_get_supported_xfer_mode() dereferences dev->desc to obtain the master controller without holding bus->lock, creating a race condition that can lead to memory corruption , system instability, or denial of servi...

CVE-2026-80953

CVE-2026-80953 is a race condition in the Linux kernel's ADI i3c master driver . The function adi_i3c_master_probe() requests the IRQ and unmasks REG_IRQ_PENDING_CMDR before the controller's transfer queue lock (xferqueue.lock) and IBI state are initialized. A pending CMDR interrupt can therefore...

CVE-2026-80951

CVE-2026-80951 is an out-of-bounds write in the Linux kernel's i3c master svc driver. The function svc_i3c_master_handle_ibi() reads IBI payloads from the RX FIFO, but its loop is bounded by the hardware FIFO size rather than the per-slot max_payload_len . When a device sends more bytes than the ...

CVE-2026-80952

CVE-2026-80952 affects the Linux kernel i3c master component. The root cause is a race condition in i3c_master_unregister_i3c_devs(), which clears the device descriptor (i3cdev->dev->desc) before device_unregister() completes. During the unbind process, i3c_device_uevent() and a racing moda...

CVE-2026-80950

A use-after-free vulnerability exists in the Linux kernel's Renesas I3C driver . The driver uses an asynchronous data-transfer model: it enqueues a transfer struct and waits for completion. If a transfer times out , the waiting thread frees the struct. If an interrupt then fires, the interrupt ha...

CVE-2026-80949

CVE-2026-80949 is a memory leak in the Linux kernel's brcmfmac Wi-Fi driver. In the function brcmf_sdio_read_control() , memory allocated for buf is not freed in certain error paths, leading to unreleased kernel memory. The fix adds vfree() calls to those error paths. No CVSS score or exploitatio...

CVE-2026-80948

CVE-2026-80948 is a memory leak in the Linux kernel's iwlwifi DVM wireless driver. In iwl_op_mode_dvm_start(), error paths triggered after successful EEPROM parsing free priv->nvm_data but skip the out_free_eeprom_blob label, leaking priv->eeprom_blob. The fix reorders the error-handling la...

CVE-2026-80947

CVE-2026-80947 is a use-after-free in the Linux kernel's rtl8xxxu Wi-Fi USB driver. During teardown, rtl8xxxu_stop() failed to cancel the rx_urb_wq worker, so a worker armed by active RX traffic could dereference freed priv after ieee80211_free_hw() freed it. Two races existed: schedule_work() wa...

CVE-2026-80946

This Linux kernel vulnerability affects the FUSE-io-uring transport. The fuse_request slab cache (fuse_req_cachep) is created without a usercopy whitelist , so directly copying req->in.h to the ring or req->out.h back from the ring trips CONFIG_HARDENED_USERCOPY , triggering a kernel panic ...
