CVE-2026-43463

In the Linux kernel, the following vulnerability has been resolved: rxrpc, afs: Fix missing error pointer check after rxrpckernellookuppeer rxrpckernellookuppeer can also return error pointers in addition to NULL, so just checking for NULL is not sufficient. Fix this by: 1 Changing...

CVE-2026-43462 net: spacemit: Fix error handling in emac_tx_mem_map()

In the Linux kernel, the following vulnerability has been resolved: net: spacemit: Fix error handling in emactxmemmap The DMA mappings were leaked on mapping error. Free them with the existing emacfreetxbuf function...

CVE-2026-43462

CVE-2026-43462 affects the Linux kernel spacemit network driver. An error in the function emac_tx_mem_map() could leak DMA mappings on a mapping failure. This resource mismanagement may lead to a denial of service, impacting system availability. The published fix frees the leaked DMA mappings usi...

CVE-2026-43461

In the Linux kernel, the following vulnerability has been resolved: spi: amlogic: spifc-a4: Fix DMA mapping error handling Fix three bugs in amlsfcdmabuffersetup error paths: 1. Unnecessary goto: When the first DMA mapping sfc-daddr fails, nothing needs cleanup. Use direct return instead of goto...

CVE-2026-43461

CVE-2026-43461 affects the Linux kernel’s spi: amlogic: spifc-a4 driver, specifically aml_sfc_dma_buffer_setup(). The patch fixes three DMA mapping error paths: (1) removing an unnecessary goto when sfc->daddr mapping fails, (2) preventing a double-unmap when info DMA mapping fails by avoiding...

CVE-2026-43451

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinkqueue: fix entry leak in bridge verdict error path nfqnlrecvverdict calls finddequeueentry to remove the queue entry from the queue data structures, taking ownership of the entry. For PFBRIDGE packets, it then...

CVE-2026-43451

Summary of CVE-2026-43451 (Linux kernel): The nfnetlink_queue entry leak occurs in the bridge verdict error path. When nfqnl_recv_verdict() dequeues an entry for PF_BRIDGE packets and nfqa_parse_bridge() returns an error (for example VLAN TCI missing when VLAN is present), the code returns withou...

CVE-2026-43445 e1000/e1000e: Fix leak in DMA error cleanup

In the Linux kernel, the following vulnerability has been resolved: e1000/e1000e: Fix leak in DMA error cleanup If an error is encountered while mapping TX buffers, the driver should unmap any buffers already mapped for that skb. Because count is incremented after a successful mapping, it will...

CVE-2026-43445

In the Linux kernel, the following vulnerability has been resolved: e1000/e1000e: Fix leak in DMA error cleanup If an error is encountered while mapping TX buffers, the driver should unmap any buffers already mapped for that skb. Because count is incremented after a successful mapping, it will...

CVE-2026-43445

CVE-2026-43445 is a Linux kernel vulnerability in the e1000/e1000e drivers (and potentially igbvf) where a DMA mapping error cleanup leak could occur. The root cause was an off-by-one condition in the dma_error path: count was decremented before the loop, so if any TX buffer mappings succeeded be...

CVE-2026-43443

In the Linux kernel, the following vulnerability has been resolved: ASoC: amd: acp-mach-common: Add missing error check for clock acquisition The acpcardrt5682init and acpcardrt5682sinit functions did not check the return values of clkget. This could lead to a kernel crash when the invalid pointe...

CVE-2026-43444

CVE-2026-43444 is a Linux kernel vulnerability in the drm/amdkfd component. The issue arises from improper error handling in which a buffer object (bo) is not released if a queue update fails, leaving the BO unreserved. The description across multiple sources notes that the error path should unre...

CVE-2026-43444 drm/amdkfd: Unreserve bo if queue update failed

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Unreserve bo if queue update failed Error handling path should unreserve bo then return failed. cherry picked from commit c24afed7de9ecce341825d8ab55a43a254348b33...

CVE-2026-43443

CVE-2026-43443 involves the Linux kernel ASoC AMD ACP Mach common driver. The acp_card_rt5682_init() and acp_card_rt5682s_init() functions did not validate clk_get() returns, risking dereferencing invalid pointers and kernel crash. The patch changes clock acquisition to devm_clk_get() and adds IS...
