CVE-2026-68235

The CVE refers to drm/amd/display (dce100) in the Linux kernel. Root cause: when assigning a stream encoder for a second DisplayPort MST stream on DCE8-class ASICs, if the preferred digital encoder is already acquired, the code can fall back to an analog DAC encoder whose funcs table lacks DP hoo...

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: dce100: skip non-DP stream encoders for DP MST On DCE8-class ASICs e.g. Bonaire, the resource pool contains digital DIG stream encoders plus one analog DAC encoder. When assigning a stream encoder for a second...

CVE-2026-68188

CVE-2026-68188 : In the Linux kernel Bluetooth RFCOMM path, a race caused use-after-free in rfcomm_send_rpn when rfcomm_tty_set_termios tests dlc->session without holding rfcomm_mutex and the DLC/session is freed by krfcommd. The fix adds rfcomm_dlc_send_rpn() that holds rfcomm_mutex while ver...

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: validate ranges in damonsetregions DAMON core logic assumes zero length regions don't exist. However, a few DAMON API callers including DAMONSYSFS, DAMONRECLAIM and DAMONLRUSORT allow users to set empty monitoring...

CVE-2026-68165

The CVE affects the Linux kernel DAMON subsystem (mm/damon/core) where damon_set_regions() did not validate zero-length regions created by certain callers (DAMON_SYSFS, DAMON_RECLAIM, DAMON_LRU_SORT). This could trigger WARN_ONCE on CONFIG_DAMON_DEBUG_SANITY and cause a divide-by-zero in damon_me...

EUVD-2026-55550

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: disallow overlapping input ranges for damonsetregions damonsetregions assumes the input ranges are sorted by the address and don't overlap each other. Hence the assumption was initially to be explicitly validated...

CVE-2026-68164

The CVE concerns the Linux kernel DAMON subsystem, specifically the function damon_set_regions() in mm/damon/core. The root cause was that input ranges were assumed to be sorted and non-overlapping, but a prior commit removed validation, allowing overlapping ranges. The consequence can be odd mon...
