CVE-2026-68288

A flaw was found in the Linux kernel's dropmonitor module. This vulnerability allows for information disclosure due to uninitialized padding bytes in the NETDMATTRPAYLOAD attribute. When the packet payload length is not a multiple of four, these uninitialized bytes are leaked to user space. A loc...

CVE-2026-19146

A flaw was found in Google Chrome on Android, specifically within its Graphics Processing Unit GPU component. A remote attacker, after compromising the browser's renderer process, could exploit an uninitialized memory vulnerability by tricking a user into visiting a specially crafted HTML page...

CVE-2026-11809

The UpdateHub OTA client in subsys/mgmt/updatehub/updatehub.c contains an out-of-bounds / uninitialized-memory read in zimplupdatehubprobe. The probe response from the UpdateHub server is copied into a heap buffer metadata that is correctly NUL-terminated, but a second buffer metadatacopy is...

CVE-2026-11809

CVE-2026-11809 (Zephyr UpdateHub OTA client) : The UpdateHub probe in subsys/mgmt/updatehub/updatehub.c uses a second heap buffer (metadata_copy) via memcpy(metadata_copy, metadata, strlen(metadata)) without zeroing. This omits the terminating NUL, so a subsequent json_obj_parse(metadata_copy, st...

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix potential buffer underflow in ath11khalrxmsdulistget When the first entry in msdudetails has a zero buffer address, the code accesses msdudetailsi - 1 with i == 0, causing a buffer underflow. Fix similarly to...

CVE-2026-68089 iio: core: fix uninitialized data in debugfs

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-2026-71394

GNU Emacs for Android improperly validates the table header input in sfntreadtabledirectory in src/sfnt.c. Due to an incorrect comparison variable in the read-length check, a crafted font file that claims to contain more table directory entries than actually present causes the parser to return a...

CVE-2026-71394

CVE-2026-71394 affects GNU Emacs for Android. The flaw in sfnt_read_table_directory() (src/sfnt.c) arises from an incorrect read-length check, allowing a crafted font to report more table directory entries than exist and return a structure with uninitialized heap memory in table directory entries...
