CVE-2026-98170

The Linux kernel contains an out-of-bounds read vulnerability in the smb: client component within the move_smb2_ea_to_cifs() function. The root cause is an insufficient loop condition (while (src_size > 0)) that allows iteration to continue even when the remaining src_size is too small to hold...

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential OOB read in smb3enumsnapshots If snapshotarraysize is smaller than GMTTOKENSIZE, smb3enumsnapshots sets retdatalen to sizeofstruct smbsnapshotarray without verifying the actual length of the server's...

CVE-2026-98169

The Linux kernel contains an out-of-bounds (OOB) read vulnerability in the smb3_enum_snapshots() function of the SMB client. The issue arises because the function fails to verify the actual length of a server's reply when snapshot_array_size is smaller than GMT_TOKEN_SIZE. Since SMB2_ioctl() does...

CVE-2026-98168

The Linux kernel contains a vulnerability in the SMB client component within the cifs_query_reparse_point() function. The root cause is an insufficient bounds check where the code verifies that the start pointer is within the response but fails to ensure at least 8 bytes remain for the reparse_da...

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix reparse buffer bounds in cifsqueryreparsepoint In cifsqueryreparsepoint, the start = end check before casting to struct reparsedatabuffer only ensures the start pointer is within the response. It fails to verify...

CVE-2026-98167

The Linux kernel SMB client contains a vulnerability in receive_encrypted_standard() where server->total_read incorrectly maintains the full decrypted frame size while processing sub-PDUs of a compound encrypted frame . This oversight causes cifs_handle_standard() to pass an incorrect size to ...

EUVD-2026-93095

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix server-totalread for compound encrypted PDUs In receiveencryptedstandard, server-totalread is left at the full decrypted frame size when walking sub-PDUs of a compound encrypted frame. As a result,...

CVE-2026-98165

The Linux kernel 's drm/amdgpu driver contains a vulnerability related to the BAR0 fallback read path. This path was originally implemented as a workaround for SR-IOV VFs where the VRAM aperture is unavailable during early initialization. The fix involves restricting this workaround specifically ...

CVE-2026-98166

The Linux kernel contains a vulnerability in the drm/ttm component where swapped-out resources fail to leave their bulk_move range. The root cause is that a previous commit incorrectly moved bookkeeping logic, causing the ttm_resource_del_bulk_move_unevictable() and ttm_resource_move_to_lru_tail(...
