EUVD-2026-55270

In the Linux kernel, the following vulnerability has been resolved: iio: core: fix uninitialized data in debugfs If ppos is non-zero then simplewritetobuffer will not initialize the start of buf. Non zero values for ppos aren't going to work anyway. Test for them at the start of the function and...

CVE-2026-68089

The CVE-2026-68089 entry concerns the Linux kernel iio core debugfs handling. It documents a vulnerability where uninitialized data could be exposed when *ppos is non-zero, because simple_write_to_buffer() would not initialize buf[]. The fix adds a test for non-zero *ppos at the start of the affe...

PT-2026-69490

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the iio core component where uninitialized data can occur in debugfs. This happens because when the ppos variable is non-zero, the simple write to buffer function fail...

CVE-2026-68089: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: iio: core: fix uninitialized data in debugfs If ppos is non-zero then simplewritetobuffer will not initialize the start of buf. Non zero values for ppos aren't going to work anyway. Test for them at the start of the function and...

SUSE CVE-2026-70631

FFmpeg versions from 0.5 up to, but not including, 9.0 contain an uninitialized heap memory disclosure vulnerability in the native TIFF decoder in libavcodec/tiff.c. An attacker who can cause FFmpeg to decode a crafted TIFF file can supply a valid Deflate-compressed strip that terminates...

CVE-2026-64264

A flaw was found in the Linux kernel's FUSE Filesystem in Userspace component. An error handling vulnerability in the fuseuringcommit function allows a positive error code to overwrite a critical negative error, causing FUSE operations to be incorrectly reported as successful. This can lead to FU...

FreeBSD Security Advisory - FreeBSD-SA-26:51.ktimer

FreeBSD Security Advisory - To retrieve the previous timer value, the kernel calls realtimergettime, which obtains the current time for the timer's clock. For a timer using CLOCKTAI this can fail when no TAI offset has been configured, but the error return was not checked, so the uninitialized...

CVE-2026-64264

In the Linux kernel, the following vulnerability has been resolved: fuse-uring: fix EFAULT clobber in fuseuringcommit copyfromuser returns the number of bytes not copied as an unsigned residual on failure 1..sizeofstruct fuseoutheader. fuseuringcommit stores that residual in ssizet err, sets...

PT-2026-64581

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the hfs/hfsplus components where the hfs bnode read function can return early without writing to the output buffer. This occurs when is bnode offset valid fails or whe...

SUSE CVE-2026-63870

In the Linux kernel, the following vulnerability has been resolved: ieee802154: 6lowpan: only accept IPv6 packets in lowpanxmit The aoe driver or similar generates a non-IPv6 packet e.g., ETHPAOE and queues it for transmission via devqueuexmit on a 6LoWPAN interface configured by the user or test...

CVE-2026-63870

A flaw was found in the Linux kernel's 6LoWPAN IPv6 over Low-Power Wireless Personal Area Networks module. When a non-IPv6 packet is transmitted over a 6LoWPAN interface, the system attempts to process uninitialized data. This can lead to system instability or a denial of service, making the syst...

CVE-2026-53400

A flaw was found in the Linux kernel, specifically within its I2C Inter-Integrated Circuit core component. This vulnerability arises from a timing issue during the registration of I2C adapters, where an adapter could be accessed before it is fully prepared. This premature access to uninitialized...

CVE-2026-63961

In the Linux kernel, the following vulnerability has been resolved: usb: typec: altmodes/displayport: validate count before reading Status Update VDO A broken/malicious device can send the incorrect count for a status update VDO, which will cause the kernel to read uninitialized stack data and se...

CVE-2026-63936

In the Linux kernel, the following vulnerability has been resolved: iio: adc: mt6359: fix unchecked return value in mt6358readimp In mt6358readimp, the variable valv is passed to regmapread but the return value is not checked. If the read fails, valv remains uninitialized and its random stack...

CVE-2026-63934

CVE-2026-63870

The CVE-2026-63870 issue affects linux ieee802154/6lowpan where non‑IPv6 packets (e.g., from an aoe driver) queued for transmission on a 6LoWPAN interface bypass the IPv6 check. The header creation function returns early and leaves lowpan_addr_info uninitialized in skb headroom; the transmit path...
