| CVE-2025-39941 | 1 Linux | 1 Linux Kernel | 2026-07-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: zram: fix slot write race condition Parallel concurrent writes to the same zram index result in leaked zsmalloc handles. Schematically we can have something like this: CPU0 CPU1 zram_slot_lock() zs_free(handle) zram_slot_lock() zram_slot_lock() zs_free(handle) zram_slot_lock() compress compress handle = zs_malloc() handle = zs_malloc() zram_slot_lock zram_set_handle(handle) zram_slot_lock zram_slot_lock zram_set_handle(handle) zram_slot_lock Either CPU0 or CPU1 zsmalloc handle will leak because zs_free() is done too early. In fact, we need to reset zram entry right before we set its new handle, all under the same slot lock scope. | ||||

| In the Linux kernel, the following vulnerability has been resolved: ASoC: simple-card-utils: Don't use __free(device_node) at graph_util_parse_dai() commit 419d1918105e ("ASoC: simple-card-utils: use __free(device_node) for device node") uses __free(device_node) for dlc->of_node, but we need to keep it while driver is in use. Don't use __free(device_node) in graph_util_parse_dai(). | ||||
| CVE-2025-39928 | 1 Linux | 1 Linux Kernel | 2026-07-30 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: i2c: rtl9300: ensure data length is within supported range Add an explicit check for the xfer length to 'rtl9300_i2c_config_xfer' to ensure the data length isn't within the supported range. In particular a data length of 0 is not supported by the hardware and causes unintended or destructive behaviour. This limitation becomes obvious when looking at the register documentation [1]. 4 bits are reserved for DATA_WIDTH and the value of these 4 bits is used as N + 1, allowing a data length range of 1 <= len <= 16. Affected by this is the SMBus Quick Operation which works with a data length of 0. Passing 0 as the length causes an underflow of the value due to: (len - 1) & 0xf and effectively specifying a transfer length of 16 via the registers. This causes a 16-byte write operation instead of a Quick Write. For example, on SFP modules without write-protected EEPROM this soft-bricks them by overwriting some initial bytes. For completeness, also add a quirk for the zero length. [1] https://svanheule.net/realtek/longan/register/i2c_mst1_ctrl2 | ||||

| CVE-2025-39906 | 1 Linux | 1 Linux Kernel | 2026-07-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: remove oem i2c adapter on finish Fixes a bug where unbinding of the GPU would leave the oem i2c adapter registered resulting in a null pointer dereference when applications try to access the invalid device. (cherry picked from commit 89923fb7ead4fdd37b78dd49962d9bb5892403e6) | ||||
| CVE-2025-39897 | 1 Linux | 1 Linux Kernel | 2026-07-30 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: net: xilinx: axienet: Add error handling for RX metadata pointer retrieval Add proper error checking for dmaengine_desc_get_metadata_ptr() which can return an error pointer and lead to potential crashes or undefined behaviour if the pointer retrieval fails. Properly handle the error by unmapping DMA buffer, freeing the skb and returning early to prevent further processing with invalid data. | ||||
| CVE-2025-39882 | 1 Linux | 1 Linux Kernel | 2026-07-30 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: fix potential OF node use-after-free The for_each_child_of_node() helper drops the reference it takes to each node as it iterates over children and an explicit of_node_put() is only needed when exiting the loop early. Drop the recently introduced bogus additional reference count decrement at each iteration that could potentially lead to a use-after-free. | ||||
| CVE-2025-39872 | 1 Linux | 1 Linux Kernel | 2026-07-30 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: hsr: hold rcu and dev lock for hsr_get_port_ndev hsr_get_port_ndev calls hsr_for_each_port, which need to hold rcu lock. On the other hand, before return the port device, we need to hold the device reference to avoid UaF in the caller function. | ||||

| In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: edma: Fix memory allocation size for queue_priority_map Fix a critical memory allocation bug in edma_setup_from_hw() where queue_priority_map was allocated with insufficient memory. The code declared queue_priority_map as s8 (*)[2] (pointer to array of 2 s8), but allocated memory using sizeof(s8) instead of the correct size. This caused out-of-bounds memory writes when accessing: queue_priority_map[i][0] = i; queue_priority_map[i][1] = i; The bug manifested as kernel crashes with "Oops - undefined instruction" on ARM platforms (BeagleBoard-X15) during EDMA driver probe, as the memory corruption triggered kernel hardening features on Clang. Change the allocation to use sizeof(*queue_priority_map) which automatically gets the correct size for the 2D array structure. | ||||

| In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: fix use-after-free in cmp_bss() Following bss_free() quirk introduced in commit 776b3580178f ("cfg80211: track hidden SSID networks properly"), adjust cfg80211_update_known_bss() to free the last beacon frame elements only if they're not shared via the corresponding 'hidden_beacon_bss' pointer. | ||||
| CVE-2025-39849 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2026-07-30 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: sme: cap SSID length in __cfg80211_connect_result() If the ssid->datalen is more than IEEE80211_MAX_SSID_LEN (32) it would lead to memory corruption so add some bounds checking. | ||||

| In the Linux kernel, the following vulnerability has been resolved: ax25: properly unshare skbs in ax25_kiss_rcv() Bernard Pidoux reported a regression apparently caused by commit c353e8983e0d ("net: introduce per netns packet chains"). skb->dev becomes NULL and we crash in __netif_receive_skb_core(). Before above commit, different kind of bugs or corruptions could happen without a major crash. But the root cause is that ax25_kiss_rcv() can queue/mangle input skb without checking if this skb is shared or not. Many thanks to Bernard Pidoux for his help, diagnosis and tests. We had a similar issue years ago fixed with commit 7aaed57c5c28 ("phonet: properly unshare skbs in phonet_rcv()"). | ||||
| CVE-2025-39841 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2026-07-30 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix buffer free/clear order in deferred receive path Fix a use-after-free window by correcting the buffer release sequence in the deferred receive path. The code freed the RQ buffer first and only then cleared the context pointer under the lock. Concurrent paths (e.g., ABTS and the repost path) also inspect and release the same pointer under the lock, so the old order could lead to double-free/UAF. Note that the repost path already uses the correct pattern: detach the pointer under the lock, then free it after dropping the lock. The deferred path should do the same. | ||||

| In the Linux kernel, the following vulnerability has been resolved: batman-adv: fix OOB read/write in network-coding decode batadv_nc_skb_decode_packet() trusts coded_len and checks only against skb->len. XOR starts at sizeof(struct batadv_unicast_packet), reducing payload headroom, and the source skb length is not verified, allowing an out-of-bounds read and a small out-of-bounds write. Validate that coded_len fits within the payload area of both destination and source sk_buffs before XORing. | ||||

| In the Linux kernel, the following vulnerability has been resolved: smb: client: fix race with concurrent opens in rename(2) Besides sending the rename request to the server, the rename process also involves closing any deferred close, waiting for outstanding I/O to complete as well as marking all existing open handles as deleted to prevent them from deferring closes, which increases the race window for potential concurrent opens on the target file. Fix this by unhashing the dentry in advance to prevent any concurrent opens on the target. | ||||
