    ecryptfs: reject oversized encrypted_key_size in parse_tag_3_packet

    In the Linux kernel, the following vulnerability has been resolved: ecryptfs: reject oversized encrypted_key_size in parse_tag_3_packet parse_tag_3_packet() set encrypted_key_size from the Tag 3 packet body without bounding it against ECRYPTFS_MAX_KEY_BYTES (64). When encrypted_key_size > 64, decrypt_passphrase_encrypted_session_key() sets decrypted_key_size = encrypted_key_size and performs two out-of-bounds writes: 1. crypto_skcipher_decrypt() writes encrypted_key_size bytes into decrypted_key[64] via scatterlist, overflowing into the parent ecryptfs_auth_tok struct. 2. memcpy(crypt_stat->key, decrypted_key, decrypted_key_size) wri

    ecryptfs: reject too-small tag 70 packets

    In the Linux kernel, the following vulnerability has been resolved: ecryptfs: reject too-small tag 70 packets ecryptfs_parse_tag_70_packet() subtracts fixed metadata fields from the parsed packet body size to derive the encrypted filename size. A malformed packet with a body smaller than those fixed fields can underflow that size calculation. Reject tag 70 packets before the subtraction unless the body contains the signature, cipher code, and at least one byte of encrypted filename data.

    ecryptfs: release message context on send failure

    In the Linux kernel, the following vulnerability has been resolved: ecryptfs: release message context on send failure ecryptfs_send_message_locked() moves a message context from the free list to the allocated list before sending the request to the userspace daemon. If ecryptfs_send_miscdev() fails, the context is left on the allocated list and cannot be reused. Move it back to the free list on failure and clear the caller's pointer.

    ext2: Fix lost inode updates for IS_SYNC inodes

    In the Linux kernel, the following vulnerability has been resolved: ext2: Fix lost inode updates for IS_SYNC inodes ext2_setsize() and ext2_xattr_set2() had a construct like: if (IS_SYNC(inode)) { sync_inode_metadata(inode, 1); } else { mark_inode_dirty(inode); } which leads to lost inode updates for IS_SYNC inodes because sync_inode_metadata() does anything only if the inode is already dirty and hence inode updates may be simply lost. Fix the problem by unconditionally marking the inode dirty and *then* call sync_inode_metadata().

    fbdev: omapfb: panel-dsi-cm: initialize lock before registering display

    In the Linux kernel, the following vulnerability has been resolved: fbdev: omapfb: panel-dsi-cm: initialize lock before registering display dsicm_probe() registers the display before initializing ddata->lock. Once omapdss_register_display() publishes the display, another consumer can reach a dsicm callback that takes this mutex while it is still uninitialized. Initialize the mutex before registering the display so the published callbacks always see a valid lock.

    In the Linux kernel, the following vulnerability has been resolved: fbdev: ssd1307fb: defer I2C transfers from damage callbacks The fbdev damage callbacks may run from fbcon while printk has disabled preemption.

    fbdev: uvesafb: unregister connector callback on init failure

    In the Linux kernel, the following vulnerability has been resolved: fbdev: uvesafb: unregister connector callback on init failure uvesafb_init() registers the v86d connector callback before registering the platform driver. If platform_driver_register() fails, the function returns the error directly and leaves the connector callback registered. The later platform-device failure path already unregisters the callback. Add the same cleanup before the final return when platform-driver registration fails. This issue was identified during our ongoing static-analysis research while reviewing kernel code.

    fsnotify: Fix stale object mask after concurrent mark updates

    In the Linux kernel, the following vulnerability has been resolved: fsnotify: Fix stale object mask after concurrent mark updates When a mark gets a new event bit, fanotify and inotify may avoid recalculating the object mask if the cached aggregate already contains that bit. This is racy with a recalculation triggered by a concurrent update to another mark on the same connector. The concurrent scan can read the mark before the new bit is added, while the updater reads the old aggregate before that scan publishes its result. The updater then skips recalculation and the scan publishes a mask without the bit, leaving the object mask stale aft

    hsi: omap_ssi_core: fix missing DMA mask setup for SSI controller device

    In the Linux kernel, the following vulnerability has been resolved: hsi: omap_ssi_core: fix missing DMA mask setup for SSI controller device The OMAP SSI driver uses a synthetic HSI controller device allocated via hsi_alloc_controller(), which does not go through the normal OF/platform device initialization path. As a result, the embedded struct device does not have a DMA mask initialized by default. After recent DMA API hardening changes, dma_map_sg() and related helpers now require a valid dma_mask to be present, otherwise the driver may crash or trigger warnings when attempting DMA mapping operations. Fix this by explicitly initializi

The TRIM descriptor is built by ata_format_dsm_trim_descr() into the 2048-byte ata_scsi_rbuf staging buffer, and the number of bytes copied is compared against the logical sector size by the caller: size = ata_format_dsm_trim_descr(scmd, trmax, block, n_block); if (size != len) /* len == sdp->sector_size */ goto invalid_param_len; ata_format_dsm_trim_descr() clamps

    auxdisplay: charlcd: cancel backlight work on registration failure

    In the Linux kernel, the following vulnerability has been resolved: auxdisplay: charlcd: cancel backlight work on registration failure With CONFIG_CHARLCD_BL_FLASH, charlcd_init() schedules bl_work before charlcd_register() calls misc_register(). If registration fails, the caller frees the charlcd object while delayed work still contains its address. Add charlcd_deinit() to cancel the delayed work and turn the backlight off. Use it for both registration rollback and normal unregistration.

    bnx2x: fix double free in bnx2x_init_firmware() error path

The cleanup function bnx2x_release_firmware() frees the same three pointers unconditionally, so if init_firmware fails and release_firmware is later called (e.g. from __bnx2x_remove or through the function state machine), all three are freed a second time. Set each pointer to NULL after kfree() in the error path so that the subsequent kfree(NULL) in bnx2x_release_firmware() is a safe no-o

    In the Linux kernel, the following vulnerability has been resolved: bpf: Disable preemption in __bpf_get_stack get_perf_callchain() returns a per-CPU perf_callchain_entry buffer and releases its recursion slot via put_callchain_entry() before returning, so nothing keeps the entry reserved while __bpf_get_stack() consumes it below. A preemptible BPF program (e.g. a non-sleepable raw tracepoint program on a PREEMPT kernel, which runs under migrate_disable() but not preempt_disable()) can be scheduled out between obtaining the entry and the copy. Another task scheduled on the same CPU then reuses the same per-CPU buffer and overwrites trace->

    dm-era: fix shadowed superblock leak on take-snap failure

    In the Linux kernel, the following vulnerability has been resolved: dm-era: fix shadowed superblock leak on take-snap failure metadata_take_snap() bumps the live superblock refcount and then dm_tm_shadow_block() allocates a new block for the metadata snapshot. If the subsequent dm_sm_inc_block() of writeset_tree_root or era_array_root fails, the function only unlocks the clone and returns. The newly allocated shadow block is never returned to the metadata space map, so each failed take-snap permanently leaks one metadata block. Free the clone with dm_sm_dec_block() on those error paths, matching the final step of metadata_drop_snap().

Point the mappings root at a hint block and __load_mappings() walks it through an info whose value size is 8, so element_at() strides 8 bytes over 4-byte entries and reaches offset 8160 of a 4096-byte block. get_ablock() and __shadow_ablock() ar

    jbd2: bound shrinker scans by examined checkpoint buffers

    In the Linux kernel, the following vulnerability has been resolved: jbd2: bound shrinker scans by examined checkpoint buffers The jbd2 shrinker currently accounts only checkpoint buffers that it successfully releases against nr_to_scan. Busy buffers therefore do not consume the scan budget. If a checkpoint transaction contains mostly busy buffers, the shrinker can scan its entire checkpoint list while holding journal->j_list_lock. Large checkpoint lists can result in excessive lock hold times and leave other CPUs spinning on j_list_lock, causing soft lockups or RCU stalls.
