Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: platform/chrome: crosectypec: Stale pointers have been set to zero. The function crostypecgetswitchhandles allocates four pointers when obtaining type-c switch handles. These pointers are all freed if none of them are obtained...

CVE-2026-48984

pamusb provides hardware authentication for Linux using ordinary removable media. In versions 0.9.1 and below, the xfree memory release helper in calls free without first zeroing the buffer contents, releasing heap-allocated buffers containing sensitive data — including one-time pad bytes read fr...

CVE-2026-48984

pam_usb for Linux (affected: v0.9.1 and earlier) has a memory handling flaw where xfree() frees buffers without zeroing contents, potentially leaving sensitive data (including one-time pad bytes) in freed heap memory. On systems with use-after-free or heap inspection capabilities, this could perm...

CVE-2026-48984 pam_usb: xfree() does not call explicit_bzero — sensitive cryptographic material may linger in freed heap

pamusb provides hardware authentication for Linux using ordinary removable media. In versions 0.9.1 and below, the xfree memory release helper in calls free without first zeroing the buffer contents, releasing heap-allocated buffers containing sensitive data — including one-time pad bytes read fr...

CVE-2026-46329 erofs: handle end of filesystem properly for file-backed mounts

In the Linux kernel, the following vulnerability has been resolved: erofs: handle end of filesystem properly for file-backed mounts I/O requests beyond the end of the filesystem should be zeroed out, similar to loopback devices and that is what we expect...

CVE-2026-46326

CVE-2026-46326 affects the Linux kernel driver iio: pressure: mprls0025pa. The root cause is improper initialization of the spi_transfer structure, with the patch ensuring the spi_transfer struct is zeroed out before use. The impact is high (local access with potential to read uninitialized memor...

CVE-2026-46167

In the Linux kernel, the following vulnerability has been resolved: usb: usblp: fix uninitialized heap leak via LPGETSTATUS ioctl Just like in a previous problem in this driver, usblpctrlmsg will collapse the usbcontrolmsg return value to 0/-errno, discarding the actual number of bytes transferre...

CVE-2026-46132

In the Linux kernel, the following vulnerability has been resolved: net: rtnetlink: zero iflavfbroadcast to avoid stack infoleak in rtnlfillvfinfo rtnlfillvfinfo declares struct iflavfbroadcast on the stack without initialisation: struct iflavfbroadcast vfbroadcast; The struct contains a single...

UBUNTU-CVE-2026-46182

In the Linux kernel, the following vulnerability has been resolved: pseries/papr-hvpipe: Prevent kernel stack memory leak to userspace The hdr variable is allocated on the stack and only hdr.version and hdr.flags are initialized explicitly. Because the struct paprhvpipehdr contains reserved paddi...

CVE-2026-46182 pseries/papr-hvpipe: Prevent kernel stack memory leak to userspace

In the Linux kernel, the following vulnerability has been resolved: pseries/papr-hvpipe: Prevent kernel stack memory leak to userspace The hdr variable is allocated on the stack and only hdr.version and hdr.flags are initialized explicitly. Because the struct paprhvpipehdr contains reserved paddi...

CVE-2026-46182

The CVE-2026-46182 issue affects the Linux kernel component pseries/papr-hvpipe . The root cause is that a local kernel stack variable hdr (papr_hvpipe_hdr) is allocated on the stack and only hdr.version and hdr.flags are initialized, leaving reserved padding bytes uninitialized. When copied to u...

CVE-2026-46151

CVE-2026-46151 affects the Linux kernel USB printer driver usblp, causing a heap leak in IEEE 1284 device ID handling due to short GET_DEVICE_ID responses. The issue stems from usblp_ctrl_msg() discarding actual bytes and usblp_cache_device_id_string() trusting a 2‑byte length prefix, exposing st...

SUSE CVE-2026-45858

In the Linux kernel, the following vulnerability has been resolved: ext4: don't zero the entire extent if EXT4EXTDATAPARTIALVALID1 When allocating initialized blocks from a large unwritten extent, or when splitting an unwritten extent during end I/O and converting it to initialized, there is...

SUSE CVE-2026-45892

In the Linux kernel, the following vulnerability has been resolved: ext4: drop extent cache after doing PARTIALVALID1 zeroout When splitting an unwritten extent in the middle and converting it to initialized in ext4splitextent with the EXT4EXTMAYZEROOUT and EXT4EXTDATAVALID2 flags set, it could...

SUSE CVE-2026-45944

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clear Present bit before tearing down context entry When tearing down a context entry, the current implementation zeros the entire 128-bit entry using multiple 64-bit writes. This creates a window where the hardware c...

SUSE CVE-2026-45972

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential UAF and double free in smb2openfile Zero out @erriov and @errbuftype before retrying SMB2open to prevent an UAF bug if @data != NULL, otherwise a double free...
