This is a regression relative to the async mount path, whe...

CVE-2026-52916

CVE-2026-52916 affects the Linux kernel’s BATMAN-adv frag handling. A crafted BATADV_UNICAST_FRAG packet can defragment into another BATADV_UNICAST_FRAG, causing unbounded recursion in batadv_batman_skb_recv() and leading to kernel stack exhaustion. The published description specifies that refrag...

CVE-2026-53143

In the Linux kernel DRM/AMD KFD path, CVE-2026-53143 describes a buffer overflow during CRIU checkpoint/restore for SDMA queues on Navi3x. The v11 MQD manager used the larger v11_compute_mqd buffer (2048 bytes) for KFD_MQD_TYPE_SDMA, instead of the smaller v11_sdma_mqd (512 bytes), causing a 1536...

CVE-2026-53179

CVE-2026-53179 affects the Linux kernel, specifically the staging rtl8723bs driver. The vulnerability is a buffer over-read in rtw_update_protection: a pointer inside the ies buffer is used with the full ie_length, allowing reads beyond the intended data. This is a local impact issue with HIGH se...

CVE-2026-53220

CVE-2026-53220 affects the Linux kernel netfilter bridge path. ebt_redirect_tg() dereferences br_port_get_rcu() without a NULL check when a bridge port has been removed between the original hook and an NFQUEUE reinject, potentially causing a local kernel panic. Attack surface includes scenarios w...

CVE-2026-53280 relates to the Linux kernel IOMMU path. A NULL dereference of group->domain could occur when a default IOMMU domain fails to allocate during the first probe, causing a crash at domain->ops->attach_dev in __iommu_attach_device() invoked by pci_dev_reset_iommu_done(). The co...

CVE-2026-53285

The CVE-2026-53285 issue concerns the Linux kernel drm/amd/display path, where dcn32_enable_phantom_plane() allocates ~335 KiB via kvzalloc() within an FPU-enabled, softirq-disabled region. This vmalloc flow can trigger BUG_ON(in_interrupt()), causing a kernel crash (DoS). The root cause is the l...

CVE-2026-53295

The CVE-2026-53295 entry covers a Linux kernel vulnerability in the mailbox subsystem: a missing sanity check for the mailbox channel array can lead to a dereference and an OOPS if no channel array is attached. The publicly provided connected sources confirm a patch/fix was applied in kernels and...

CVE-2026-43498

CVE-2026-43498 is a Linux kernel issue in the accel/ivpu path. The vulnerability stems from the ability to re-export imported GEM buffers; a fix adds a custom prime_handle_to_fd callback that checks if the GEM object is imported and returns -EOPNOTSUPP in that case. Under re-export scenarios, buf...

CVE-2026-53135

The CVE-2026-53135 issue affects the Linux kernel’s DRM AMD display path, specifically SDP debugfs writes. Root cause: dp_sdp_message_debugfs_write() dereferenced connector->base.state->crtc without NULL checks, potentially crashing when a connected-but-unbound connector exists (e.g., after...

The vulnerability is addressed...

CVE-2026-53258

CVE-2026-53258 affects the Linux kernel WiFi stack: when a 6 GHz split scan fails, rdev->int_scan_req is leaked because cfg80211_scan() fails before ___cfg80211_scan_done() releases it. The leak is observed in kernel mode tracing (kmemleak) and is associated with a wpa_supplicant process in th...

CVE-2026-53279

CVE-2026-53279 affects the Linux kernel driver path drm/gma500/oaktrail_lvds. The issue occurs during LVDS initialization where the code looks up an I2C adapter (via i2c_get_adapter) and may read EDID, then either uses the adapter or falls back to allocating/registering its own adapter. On late i...

CVE-2026-53282

The CVE-2026-53282 issue affects the Linux kernel’s x86/kexec purgatory code used by kexec-tools. The root cause was the purgatory path looking above the top of the stack to locate a return address for a kjump even in non-kjump kexec, which could trigger a fault/crash. A commit fixed the actual k...

Technical details for CVE-2026-53294 are not publicly available in the provided documents. Monitor for updates from Debian/Ubuntu OSV entries and kernel advisories for affected components, versions, and fixes.

CVE-2026-52915

CVE-2026-52915 concerns the Linux kernel netfilter ip6t_hbh module, where ip6t_opts may store at most IP6T_OPTS_OPTSNR (16) option descriptors but hbh_mt6_check() did not reject larger optsnr values from userspace. This allowed a potential out-of-bounds condition (UBSAN: array-index-out-of-bounds...

CVE-2026-52929

The CVE affects the Linux kernel SCTP stream handling. When ADD_OUT_STREAMS is denied, the rollback only shrinks queued chunks and lowers outcnt, leaving removed stream metadata behind. A subsequent re-add can reuse a stale ext and trigger a null-pointer dereference in the scheduler get path, pot...

CVE-2026-52942

The CVE corresponds to a Linux kernel netfilter nf_log issue where the fallback dump_mac_header() could read past the buffer if the MAC header was not set.

CVE-2026-53137

CVE-2026-53137 concerns the Linux kernel drm/amd display path where, during HDCP2.x repeater authentication over HDMI, the driver reads the sink RxStatus and uses a 10-bit message size field (max 1023) to set the read length for the ReceiverID list. The length was not clamped to the destination b...

CVE-2026-53138

The CVE-2026-53138 issue affects the Linux kernel’s drm/amd/display driver. A malformed VBIOS image can cause unbounded record-chain walk loops in bios_parser.c and bios_parser2.c due to for(;;) loops that terminate only on a 0xFF sentinel or zero record_size. This can lead to a large number of i...

CVE-2026-53155

In Linux kernels, CVE-2026-53155 relates to mm/huge_memory and device-private PMD entries. A commit (65edfda6f3f2) updated set_pmd_migration_entry() to use pmdp_huge_get_and_clear() in the softleaf case but did not adjust the function fully, causing incorrect use of pmd_write(), pmd_soft_dirty(),...

CVE-2026-53196

CVE-2026-53197

CVE-2026-53197 affects the Linux kernel xfrm/iptfs path. The bug is an ABBA deadlock: iptfs_destroy_state() cancels an hrtimer while holding a spinlock that the timer callback also tries to acquire. The output timer (iptfs_timer) path holds x->lock before cancel, while the timer callback (iptf...

CVE-2026-53199

CVE-2026-53199 pertains to the Linux kernel hv_netvsc path, where netvsc_copy_to_send_buf previously used phys_to_virt() on page buffer PFNs and could fault when fragments referenced high mem/user pages on 32-bit x86 with HIGHMEM. The fix maps pages with kmap_local_page() and reconstructs native ...

CVE-2026-53213

In the Linux kernel drm/vc4 component, CVE-2026-53213 is a memory-leak fix related to krealloc(): if krealloc() returns NULL, the original pointer may be overwritten, leaking memory. The recommended pattern is to assign krealloc() to a temporary variable, check for NULL, then update the original ...

CVE-2026-53219

The CVE-2026-53219 issue affects the Linux kernel netfilter x_tables path. The root cause is that native/compat get-entries copied the fixed rule entry header to userspace before sanitizing and overwriting the counter fields, exposing the percpu allocation address (pcnt) in SMP environments. The ...

CVE-2026-53226

The CVE-2026-53226 issue affects the Linux kernel GPIO Rockchip driver: generic IRQ chips allocated via irq_alloc_domain_generic_chips() are not freed on driver removal, leaving domain generic chips and the global gc_list leaked and potentially visited later by suspend/resume/shutdown callbacks, ...

CVE-2026-53227

CVE-2026-53227 affects the Linux kernel net/openvswitch path. The issue arises when allocating the reply skb after taking ovs_mutex, where an error path can leave the skb with an ERR_PTR and later free it during cleanup, leading to a possible invalid free. The fix sets the pointer to NULL after s...

CVE-2026-53229

The CVE-2026-53229 issue concerns the Linux kernel mlx5e driver: on XDP_TX transmit failure, DMA mappings are not properly unmapped and XDP frames are not freed, causing a potential DMA/resource leak. The description specifies that in mlx5e_xmit_xdp_buff(), when sq->xmit_xdp_frame() returns fa...

CVE-2026-53242

CVE-2026-53242 affects the Linux kernel ALSA PCM path (snd_pcm_drain) on linked streams.
