CVE-2026-74393 drm/syncobj: Fix memory leak in drm_syncobj_find_fence()

In the Linux kernel, the following vulnerability has been resolved: drm/syncobj: Fix memory leak in drmsyncobjfindfence Commit 18226ba52159 "drm/syncobj: reject invalid flags in drmsyncobjfindfence" forgot to take into account the fact that drmsyncobjfind takes a reference to syncobj and returns...

CVE-2026-74393

In the Linux kernel DRM subsystem, a memory leak was fixed in drm_syncobj_find_fence(). The root cause was that drm_syncobj_find() takes a reference to a syncobj and the function could return early without dropping that reference, leaking memory. The fix (commit 18226ba52159) also changes handlin...

In the Linux kernel, the following vulnerability has been resolved: dm: limit target bio polling to one shot dmpollbio is the -pollbio callback for a stacked dm device. The caller only knows about the dm queue, so it may decide to do a spinning poll if it thinks a single queue is being polled...

CVE-2026-74391

In the Linux kernel, the following vulnerability has been resolved: tracing: Bound synthetic-field strings with seqbuf The synthetic field helpers build a prefixed synthetic variable name and a generated hist command in fixed MAXFILTERSTRVAL buffers. The current code appends those strings with ra...

CVE-2026-74392 dm: limit target bio polling to one shot

CVE-2026-74392

Summary of CVE-2026-74392 (Linux kernel, device-mapper): The issue involves the dm_poll_bio() callback used by stacked dm devices. The caller only knows about the dm queue and could initiate spinning polls, passing flags unchanged to the mapped clone, which may cause blk_mq_poll() to spin on a ta...

CVE-2026-74391

In CVE-2026-74391, the Linux kernel tracing subsystem is affected by a buffer-overflow risk in synthetic-field string construction. The vulnerability arises because synthetic field helpers append strings with strcat() to fixed MAX_FILTER_STR_VAL buffers, allowing long key lists, field names, or s...

CVE-2026-74390

In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix out-of-bounds write in irdmacopyuserpgaddrs The irdmacopyuserpgaddrs function loops through all of the umem DMA blocks to populate the PBLEs and will stop when either the last DMA block is reached or palloc-totalc...

CVE-2026-74390

CVE-2026-74390 affects the Linux kernel’s RDMA/irdma path. The vulnerability stems from an out-of-bounds write in irdma_copy_user_pgaddrs, which iterates over umem DMA blocks to fill PBLEs. When irdma_setup_pbles is called with lvl==0, the loop may not exit properly if palloc->total_cnt == 0, ...
