CVE-2026-64453

CVE-2026-64453 affects the Linux kernel USB subsystem (usbio) where usbio_disconnect() could use a freed object while iterating the usbio->cli_list in reverse during client teardown, leading to slab-use-after-free (KASAN) reported in the vulnerability validation. The root cause is iterating wi...

CVE-2026-64452 6lowpan: fix NHC entry use-after-free on error path

In the Linux kernel, the following vulnerability has been resolved: 6lowpan: fix NHC entry use-after-free on error path lowpannhcdouncompression looks up an NHC descriptor while holding lowpannhclock. If the descriptor has no uncompress callback, the error path drops the lock before printing...

CVE-2026-64452

CVE-2026-64452 (Linux kernel 6LoWPAN) involves a race condition in 6LoWPAN’s Next Header Compression (NHC) handling that can cause a use-after-free in lowpan_nhc_do_uncompression when an NHC descriptor is freed while another path accesses nhc->name in an error path. The issue arises from holdi...

CVE-2026-64451

CVE-2026-64451 (Linux kernel) resolves a NULL pointer dereference in tracing: func_set_flag() dereferences tr->current_trace_flags before verifying the active tracer. If the function tracer is not active (e.g., switched to wakeup_rt), current_trace_flags can be NULL, causing a crash. Call path...

CVE-2026-64451 tracing: Fix NULL pointer dereference in func_set_flag()

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix NULL pointer dereference in funcsetflag funcsetflag dereferences tr-currenttraceflags before verifying that the current tracer is actually the function tracer. When the active tracer has been switched away from...

CVE-2026-64450 tipc: fix out-of-bounds read in broadcast Gap ACK blocks

In the Linux kernel, the following vulnerability has been resolved: tipc: fix out-of-bounds read in broadcast Gap ACK blocks A broadcast PROTOCOL/STATEMSG can carry a Gap ACK blocks record in its data area. tipcgetgapackblks only verifies that the record's len field is self-consistent with its...

CVE-2026-64449

CVE-2026-64449 relates to the Linux kernel staging/vme_user code. The vulnerability arises because the SLAVE-path helpers buffer_to_user() and buffer_from_user() copy count bytes using an unsafe offset (*ppos) into a fixed-size kern_buf (128 KiB), without bounding *ppos + count against size_buf. ...

CVE-2026-64449 staging: vme_user: bound slave read/write to the kern_buf size

In the Linux kernel, the following vulnerability has been resolved: staging: vmeuser: bound slave read/write to the kernbuf size The SLAVE-path helpers buffertouser and bufferfromuser copy 'count' bytes into/out of the fixed-size kernbuf sizebuf == PCIBUFSIZE == 0x20000, 128 KiB using ppos as the...

CVE-2026-64448 smb: client: restrict implied bcc[0] exemption to responses without data area

In the Linux kernel, the following vulnerability has been resolved: smb: client: restrict implied bcc0 exemption to responses without data area smb2checkmessage has a long-standing quirk that accepts a response whose calculated length is one byte larger than the bytes actually received "server ca...

EUVD-2026-48791

In the Linux kernel, the following vulnerability has been resolved: staging: media: ipu7: fix double-free and use-after-free in error paths In both ipu7isysinit and ipu7psysinit, pdata is allocated and then passed to ipu7businitializedevice, which stores it in adev-pdata. The ipu7busrelease...

CVE-2026-64447

CVE-2026-64447 maps to a Linux kernel issue in staging: ipu7 where pdata allocated in ipu7_isys_init() and ipu7_psys_init() can be freed twice via kfree pData in error paths. The two faulty paths are: (1) ipu7_mmu_init() fail leads to put_device() dropping refcount and freeing pdata via ipu7_bus_...

CVE-2026-64448

Summary (CVE-2026-64448): The Linux kernel fix addresses a SMB2 negotiation bug in CIFS/NTLM handling. A long-standing quirk in smb2_check_message() unconditionally granted a +1 length exemption for responses, even when a data area was present. This could cause the decoder to read past the receiv...
