kernel: openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size()

An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reservesfasize function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write...

kernel: KVM: VMX: Prevent RSB underflow before vmenter

In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Prevent RSB underflow before vmenter On VMX, there are some balanced returns between the time the guest's SPECCTRL value is written, and the vmenter. Balanced returns matched by a preceding call are usually ok, but it's...

Amazon Linux AMI : libtiff (ALAS-2022-1647)

The version of libtiff installed on the remote host is prior to 4.0.3-35.40. It is, therefore, affected by a vulnerability as referenced in the ALAS-2022-1647 advisory. A flaw was found in libtiffs tiffcrop utility that has a uint32t underflow that can lead to an out-of- bounds read and write. Th...

underflow in the getPrice() function can block the buy and refund in the LPDA sale

Lines of code Vulnerability details Impact In the LPDA sale the price decrease in values after each second, and when creating the sale the value of the lowest price possible is not checked, so the price could go below zero at a given timestamp which will lead to an underflow in the getPrice...

wrong configuration can lock eth in LPDA contract forever

Lines of code Vulnerability details When creating an LPDA auction there are some sanity checks of the values used for the auction. But there is no check that the auction will not cause the price calculation to underflow after a while. This calculation of the price can underflow in getPrice in...

grub2: Integer underflow in grub_net_recv_ip4_packets

A flaw was found in grub2 when handling IPv4 packets. This flaw allows an attacker to craft a malicious packet, triggering an integer underflow in grub code. Consequently, the memory allocation for handling the packet data may be smaller than the size needed. This issue causes an out-of-bands wri...
