CVE-2020-36786

The CVE-2020-36786 entry concerns a memory leak in the Linux kernel’s media: atomisp driver (staging) where, if lm3554_platform_data_func returns an error, flash object memory is leaked on the error return path. The fix introduces an error return path that frees flash and renames labels (fail2→fa...

CVE-2021-47075

The CVE-2021-47075 entry concerns the Linux kernel nvmet subsystem. A memory leak in nvmet_alloc_ctrl() could occur when cntlid_min is larger than the subsystem’s cntlid_max, because the code may jump to out_free_changed_ns_list without freeing ctrl->sqs. The patch fixes this by jumping to the...

CVE-2021-47210

The CVE-2021-47210 issue affects the Linux kernel USB Type-C subsystem (tipd) specifically in tps6598x_block_read. The fix removes a WARN_ON and ensures that calls with length exceeding the allowed maximum return an error instead of triggering a crash under panic-on-warn. This change mitigates lo...

CVE-2021-47212

CVE-2021-47212 affects the Linux kernel in the mlx5/ib stack. The issue arises in the fast unload flow where the device state enters internal error during a destroy command, causing a call path that would return EIO.

CVE-2021-47280

CVE-2021-47280 is a Linux kernel vulnerability affecting drm_getunique() in the DRM subsystem. A time-of-check-to-time-of-use (TOCTOU) error occurs by reading file_priv->master before acquiring the device master mutex, allowing a master pointer to be used after the original object may have bee...

CVE-2021-47342

CVE-2021-47342 affects the Linux kernel’s ext4 filesystem. A race during remounting a read-only, mmp-protected filesystem can cause a use-after-free (UAF) when the kmmpd thread may exit and leave sbi->s_mmp_tsk pointing at freed memory, triggering an object lifetime dereference in ext4_stop_mm...

CVE-2021-47403

CVE-2021-47403 relates to the Linux kernel ipack: ipoctal subsystem, where a reference to the carrier module was taken on every open but released only when the final reference to the tty struct dropped. The root cause is a module reference leak during tty installation/open, leading to a lingering...

CVE-2021-47425

CVE-2021-47425: Linux kernel vulnerability in i2c via ACPI resource leak. acpi_i2c_find_adapter_by_handle() calls bus_find_device() which takes a reference on the adapter that is never released, causing a reference-count leak and potentially rendering the adapter unremovable. Connected advisories...

CVE-2021-47552

CVE-2021-47552 affects the Linux kernel’s block multi-queue (blk-mq) I/O scheduling. The root issue was a race where scsi_device could be freed before blk_release_queue() ran, leading to a kernel oops. The fix cancels blk-mq dispatch work in both blk_cleanup_queue() and disk_release(), ensuring I...

CVE-2021-47563

CVE-2021-47563 (Linux kernel, ice driver): A refcount mismanagement in the ice XDP path during VSI rebuilds (e.g., ethtool set_channels) can swap bpf_prog pointers and trigger a late bpf_prog_put, potentially leading to a zero-refcount object and a kernel page fault. The issue affects the ice dri...

CVE-2021-47634

CVE-2021-47634 affects the Linux kernel ubi subsystem where a race condition can occur between ctrl_cdev_ioctl and ubi_cdev_ioctl, leading to a use-after-free reported by KASAN.

The fix replaces the overflow-prone check with the com...

CVE-2022-49312

CVE-2022-49312 (Linux kernel) : The vulnerability concerns a potential memory leak in the rtl8712 staging path. In r871xu_drv_init(), if r8712_init_drv_sw() fails, memory allocated by r8712_alloc_io_queue() in r8712_usb_dvobj_init() is not released because there is no action in r8712_usb_dvobj_de...

CVE-2022-49354

CVE-2022-49354 is a Linux kernel issue where a refcount leak in octeon_pata_OCTEON code was fixed.

CVE-2022-49367

Summary (CVE-2022-49367) In the Linux kernel, the mv88e6xxx DSA MDIO registration path contains a refcount leak. The function of_get_child_by_name() returns a node pointer with an incremented refcount, but of_node_put() is not called when finished, leaking references. mv88e6xxx_mdio_register() fo...

CVE-2022-49368

CVE-2022-49368 relates to a Linux kernel out-of-bounds read in net: ethernet: mtk_eth_soc, triggered by an invalid fsp->location that comes from user via ethtool_get_rxnfc(). The vulnerability is fixed by validating the location parameter to prevent the read, with upstream kernel patches refer...

CVE-2022-49449

The CVE-2022-49449 issue affects Linux kernel pinctrl: renesas: rzn1. The root cause is a possible null-ptr-deref when using 'res' if platform_get_resource() returns NULL. The patch defers dereferencing 'res' by performing devm_ioremap_resource() first (which validates the resource) and then uses...

CVE-2022-49508

CVE-2022-49508 affects the Linux kernel HID elan driver. The issue was a potential double free in elan_input_configured because input may be freed explicitly via input_free_device() even though the device is managed by devm_input_allocate_device(). The devm framework guarantees automatic cleanup ...

CVE-2022-49516

CVE-2022-49516 affects the Linux kernel: the ice network driver could dereference a VSI pointer returned by ice_get_vf_vsi without validating it, which could be NULL in scenarios such as resets when a VSI is removed and recreated. The published fix is to check the return value of ice_get_vf_vsi e...

CVE-2022-49720

The CVE-2022-49720 entry is valid and supported by multiple connected advisories.

CVE-2022-49729

CVE-2022-49729 affects the Linux kernel’s nfcmrvl NFC driver. The issue is a memory leak in nfcmrvl_play_deferred caused by submitting deferred URBs directly via usb_submit_urb and then unanchoring them, which could prevent proper unref and leak memory. The fix, as described in connected advisori...

CVE-2022-49733

The CVE-2022-49733 entry concerns the Linux kernel ALSA: pcm: oss – a race in snd_pcm_oss_sync() used by the OSS SNDCTL_DSP_SYNC ioctl. The vulnerability arises because snd_pcm_oss_sync() first calls snd_pcm_oss_make_ready(), then uses the params_lock mutex for the rest, allowing a thread to re-e...

CVE-2022-49850

CVE-2022-49850 affects the Linux kernel nilfs2 subsystem. A semaphore deadlock can occur when nilfs_get_block() detects metadata corruption during data-block allocation and a concurrent superblock writeback happens.

CVE-2022-49906

The CVE-2022-49906 issue affects the Linux kernel ibmvnic driver: a path in the reset handling could leak 32 bytes by not freeing the rwi structure when the last rwi in the list is processed. A fix releases the rwi memory on reset success (kernel patch 4f408e1fa6e1 and related commits). Connected...

CVE-2022-49995

The connected sources confirm CVE-2022-49995 is a Linux kernel use-after-free in writeback code when removing a disk. Specifically, wb_inode_writeback_end() could schedule work to access a freed bdi_writeback; the fix switches wb->work_lock to an irqsafe lock and checks that bdi_writeback is a...

CVE-2022-50093

CVE-2022-50093 affects the Linux kernel IOMMU VT-d code. The issue arises from using arch_test_bit() with a possibly invalid first argument when NUMA is disabled, causing a potential wild memory access after node_online() returns NUMA_NO_NODE. The fix adds an explicit check for node != NUMA_NO_NO...

CVE-2023-22997

CVE-2023-22997 affects the Linux kernel prior to 6.1.2. The vulnerability resides in module/decompress.c where the function module_get_next_page can return an error pointer, but code treats it as NULL in the error case, potentially causing a denial of service. The issue is local in scope; CVSS in...

CVE-2023-38428

CVE-2023-38428 affects the Linux kernel (ksmbd) where fs/ksmbd/smb2pdu.c does not properly validate the UserName value because it ignores the address of the security buffer, causing an out-of-bounds read.
