CVE-2026-71972: Out-of-bounds Write

U-Boot through 2026.10-rc5 contains an out-of-bounds write vulnerability in the videodisplayrle8bitmap function in drivers/video/videobmp.c. Attackers can supply a crafted RLE8-compressed BMP image to corrupt memory adjacent to the framebuffer and crash the bootloader...

CVE-2026-71973: Integer Overflow or Wraparound

U-Boot before 2026.10-rc4 contains an integer overflow vulnerability in sqfsreaddirectorytable function when allocating the directory table buffer. Attackers can supply a crafted SquashFS image with an attacker-controlled superblock metablkscount value that causes heap buffer under-allocation and...

CVE-2026-71974: Out-of-bounds Write

U-Boot before 2026.10-rc3 contains an out-of-bounds write vulnerability in readslottedpartition that fails to validate image size against partition bounds. Attackers with physical access can supply crafted boot media with oversized headers to write past the load buffer into bootloader memory on...

CVE-2026-74220: Signed to Unsigned Conversion Error

U-Boot before 2026.10-rc5 contains a buffer overflow in nfsreadreply function in net/nfs-common.c that allows attackers to corrupt memory by supplying crafted NFS READ reply lengths. A malicious NFS server can exploit signed integer handling to bypass length validation and write far past the...

CVE-2026-74221: Signed to Unsigned Conversion Error

U-Boot before 2026.10-rc5 contains a buffer overflow in nfsreadlinkreply function in net/nfs-common.c when processing NFS server responses. A malicious NFS server can send crafted READLINK replies with negative or oversized symlink length values to corrupt memory and crash the bootloader...

CVE-2026-74222: Use After Free

U-Boot before 2026.10-rc5 contains a use-after-free vulnerability in the httpcrecvcb function within the lwIP wget implementation. When HTTP data storage fails, the callback frees the connection PCB but returns ERRBUF instead of ERRABRT, causing the TCP input path to access released memory and...

CVE-2026-74225: Out-of-bounds Write

U-Boot before 2026.10-rc5 contains out-of-bounds memory access in dhcp6parseoptions that fails to validate SERVERID and CLIENTID option lengths from DHCPv6 packets. Attackers on the local network can send crafted DHCPv6 ADVERTISE or REPLY packets during netboot to corrupt memory and crash the...

Astra Linux – Vulnerability in u-boot

A issue was discovered in Das U-Boot during the period from 2019.07. There is an unbounded memcpy operation when parsing a UDP packet, due to an underflow of the netprocessreceivedpacket integer value during the ncinputpacket call...

Astra Linux – Vulnerability in u-boot

Integer overflows in memory allocation in Das U-Boot before 2025.01-rc1 occur due to a crafted squashfs filesystem using sbrk, request2size, or because ptrdifft is mishandled on x8664...

Astra Linux – Vulnerability in u-boot

In “Das U-Boot through 2020.01”, a double-free operation was detected in the cmd/gpt.c file’s dorenamegptparts function. Double-freeing can lead to a “write-what-where” condition, allowing an attacker to execute arbitrary code. NOTE: This vulnerability was introduced when attempting to fix a memo...

Astra Linux – Vulnerability in u-boot

An integer overflow occurs in the ext4fsreadsymlink function in Das U-Boot before version 2025.01-rc1. This issue arises due to the use of the zalloc function, which adds one to a le32 variable. This occurs through a crafted ext4 file system with an inode size of 0xffffffff. As a result, the mall...

Astra Linux – Vulnerability in u-boot

The U-Boot versions from 2016.09 to 2019.07-rc4 can memset too much data while reading a crafted ext4 filesystem. This results in a stack buffer overflow, potentially leading to code execution...
