UBUNTU-CVE-2026-74469

In the Linux kernel, the following vulnerability has been resolved: sctp: prevent peer transport count overflow sctpassocaddpeer increments the association's 16-bit transportcount for every new unique peer. Adding the 65,536th transport wraps the count to zero. SCTP sockdiag uses transportcount t...

UBUNTU-CVE-2026-74458

In the Linux kernel, the following vulnerability has been resolved: can: kvaserusbleaf: kvaserusbleafwaitcmd: validate received command extents The wait and bulk receive paths walk variable-length commands from a USB buffer. A nonzero command shorter than CMDHEADERLEN can still be dispatched, and...

UBUNTU-CVE-2026-74454

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Supply the overflow slot size in BPOS, not the whole bin BO size vc4overflowmemwork points BPOA at a 512KB slot inside the 16MB binner BO, but writes the size of the whole BO to BPOS. On every binner out-of-memory event...

UBUNTU-CVE-2026-74460

CVE-2026-74498

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix DMA buffer out-of-bounds write when fillmax is set When a USB audio endpoint requests full packet transfers via the fillmax descriptor flag, dataepsetparams promotes ep-curpacksize to ep-maxpacksize. However,...

UBUNTU-CVE-2026-74455

In the Linux kernel, the following vulnerability has been resolved: can: peakusb: validate uCAN receive record lengths pcanusbfddecodebuf walks uCAN records packed in one USB receive buffer. Require each record to contain the fixed header for its type, and verify CAN payload bytes before copying...

UBUNTU-CVE-2026-73194

DBI versions before 1.652 for Perl allow a heap out-of-bounds write via an unvalidated numeric placeholder that sets the binder counter in preparse. preparse reserves seven output bytes per input byte, the width of the longest ':p99999' expansion. The ':N' branch parses the number with atoisrc an...

UBUNTU-CVE-2026-74444

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: validate DRAWPRIMITIVES header size before division vmwcmddraw computes maxnum = header-size - sizeofcmd-body / sizeofdecl; where header-size is u32 and is taken straight from the user-supplied command stream. When...

CVE-2026-74470

In the Linux kernel, the following vulnerability has been resolved: scsi: scsidebug: Fix REPORT ZONES alloclen underflow OOB write respreportzones sizes the reply buffer from the CDB allocation length. The v3 fix rounds alloclen up with ALIGN before deriving the descriptor count: repmaxzones =...

UBUNTU-CVE-2026-74447

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix uint32t overflow in EOP ring buffer size alignment eopringbuffersize in struct queueproperties is a u32. In kfdqueueacquirebuffers the expected EOP buffer size is computed as ALIGNeopringbuffersize, PAGESIZE; ALIG...

UBUNTU-CVE-2026-74452

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: reject firmware sections with oversized data In panthorfwloadsectionentry, the data size to copy is calculated without validating it against the allocated sectionsize: section-data.size = hdr.data.end - hdr.data.star...

UBUNTU-CVE-2026-74446

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: hold eventmutex while checkpointing CRIU events kfdcriucheckpointevents counts the entries in p-eventidr via kfdgetnumevents, allocates an array sized to that count, and then walks the same IDR to fill it. Neither the...

UBUNTU-CVE-2026-74497

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Clamp frame size in implicit-feedback mode sndusbhandlesyncurb scales received sync packet sizes by the sender's stride and stores the result directly in outpacket-packetsizei. If a connected USB device sends an...

CVE-2026-74576

Summary of CVE-2026-74576 (Linux kernel) : The vulnerability stems from the slab allocator allowing unbounded recursion in the free path due to cycles formed when obj_exts arrays are allocated across KMALLOC_NORMAL caches. Specifically, slabs can form a cycle by allocating each other’s obj_exts a...
