CVE-2026-98171

The Linux kernel contains a vulnerability in the SMB client 's handling of compound encrypted frames within the receive_encrypted_standard() function. The issue stems from pointer lifecycle errors and insufficient bounds checking. Specifically, a use-after-free can occur because next_buffer is no...

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...

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...

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 ...

CVE-2026-98165
