UBUNTU-CVE-2026-64360

In the Linux kernel, the following vulnerability has been resolved: hfs/hfsplus: zero-initialize buffer in hfsbnoderead hfsbnoderead can return early without writing to the output buffer when isbnodeoffsetvalid fails or when checkandcorrectrequested length corrects the length to zero. Callers suc...

CVE-2026-64360

CVE-2026-64360 affecting the Linux kernel’s HFS/HFS+ code (hfs_bnode_read) was fixed by zero-initializing the output buffer at the start of hfs_bnode_read to ensure deterministic zero values across all paths. The bug allowed early returns when is_bnode_offset_valid() failed or when check_and_corr...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: asix: Proper error handling for USB read errors has been added. The Syzbot issue with the asix driver remains the same. The problem is still present—the asixreadcmd function reads fewer bytes than requested by the caller...

CVE-2026-45865 mctp i2c: initialise event handler read bytes

In the Linux kernel, the following vulnerability has been resolved: mctp i2c: initialise event handler read bytes Set a 0xff value for i2c reads of an mctp-i2c device. Otherwise reads will return "val" from the i2c bus driver. For i2c-aspeed and i2c-npcm7xx that is a stack uninitialised u8. Teste...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the usb class CCDC-WDM driver’s ability to reorder the update of desc-length during code reading,...

CVE-2026-43221 ipmi: ipmb: initialise event handler read bytes

In the Linux kernel, the following vulnerability has been resolved: ipmi: ipmb: initialise event handler read bytes IPMB doesn't use i2c reads, but the handler needs to set a value. Otherwise an i2c read will return an uninitialised value from the bus driver...

CVE-2026-43221

CVE-2026-43221 affects Linux kernel IPMI/IPMB: the event handler responsible for IPMB read bytes may fail to initialize reads, causing an I2C read to return an uninitialised value from the bus driver. This is described across multiple advisories (Root-OS-UBUNTU-2404, SUSE, Red Hat) as a patchable...

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-387783 advisory. In the Linux kernel, the following vulnerability has been resolved: netrom: check buffer length before accessing it Syzkaller reports an uninit value read from ax25c...

CVE-2025-38574

CVE-2025-38574 affects the Linux kernel PPTP transmit path (pptp_xmit). A missing bound check on skb length could allow reading uninitialized data in pptp_xmit(), similar to changes made for ppp_sync_txmunge. The issue is fixed by the upstream commit aabc6596ffb3 and related bound-checking change...
